Precision Cleaning That Stops at the Base Material
The ELASER removes rust, paint, oxides and grease by laser ablation: the beam vaporises the contamination layer and stops at the base material, leaving the substrate intact. No abrasive contact, no chemical reaction.
With fully tunable power (0–100%), one machine covers the full range — from delicate oxide removal to aggressive paint stripping — across metals, stone, brick and masonry. No equipment swaps.
Air-cooled and consumable-free, the sub-3 kg handheld scanner and up to 50 m delivery cable mean one operator takes the machine to the job.
Core Optical Parameters
Max power up to 300 W, wavelength 1550 nm, pulse energy up to 15 mJ, pulse duration 100 ns, pulse repetition rate adjustable up to 200 kHz (CW). Power is fully tunable across 0–100%, so one machine spans the full cleaning range from light oxides through to heavy coatings.
The 1550 nm wavelength sits in the retina-safe band — it is the technical foundation for the world-first ELASER-RHZ reduced hazard zone configuration.
Beam Delivery and Optics
Scanner: 2-D galvanometer with a max scan rate of 10 m/s. Scan shapes are fully programmable through the GUI, giving precise control over beam pattern for each application.
F-Theta lenses are interchangeable, covering a working distance of 75–500 mm. Lens-protection windows are included as standard and are user-replaceable, keeping optics maintenance simple and cost-effective.
Portable, Single-Operator System
The handheld scanner weighs under 3 kg. The wheeled system unit comes in at under 50 kg, requiring no fixed installation.
Delivery cable reaches up to 50 m (5 m and 15 m supplied as standard), allowing a single operator to bring the beam to the work — across a workshop floor, up a structure, or around large components — without repositioning the system unit.
Supply, Controls and Access
Power supply: 110–250 VAC single-phase. Power consumption: under 2000 W. No compressor, chiller or water circuit required — plug into a standard single-phase socket and operate.
Interface: Ethernet + touchscreen GUI. Access is password-protected with per-user logins, providing operator-level control and usage tracking from the front panel.
Compliance and Provenance
Laser class: Class IV (standard configuration) or Class I (ELASER-RHZ configuration). Certified to both CE and UKCA standards.
Designed and built in the UK. The ELASER is Made in Britain — manufactured by Woodrow Scientific Limited, the only UK-based laser cleaning manufacturer.
Metals, Stone and Masonry
The ELASER cleans across a broad range of substrates — this is not a single-material machine. Metals: steel, carbon steel, aluminium alloys, cast iron, copper, brass, bronze, titanium, galvanised. Non-metals: stone, concrete, brick, masonry. Whether the workpiece is a precision cast-iron mould, a titanium aerospace component, or a brick heritage facade, the ELASER covers it.
Rust, Paint and Beyond
The ELASER removes contamination across the full spectrum — from light surface films through to thick bonded coatings. The complete list: rust, oxides, mill scale, paint, powder coating, lacquer, primer, oil and grease, carbon and soot, mould, graffiti, adhesives and residues, tarnish, weld discolouration, release agents. This is not a rust-only or paint-only machine — one system covers the entire range.
Tunable Power, Intact Substrate
The breadth of surface and contaminant coverage is made possible by 0–100% power tunability. The same machine dials down for delicate substrates and light oxides, then dials up for thick coatings and stubborn contamination — with no equipment swap and no system reconfiguration.
The beam stops at the base material, delivering minimal substrate loss. The underlying surface stays intact, reducing rework and making the ELASER suitable for precision components, sensitive heritage stone, and fine tooling detail alongside standard industrial cleaning tasks.

The ELASER-RHZ: Laser Cleaning Without the Safety Overhead
Standard Class IV laser cleaning requires the work area to be sealed off and all personnel cleared before operation. In an open-plan facility or publicly accessible site, that is a genuine operational constraint — not a minor inconvenience.
The ELASER-RHZ removes that barrier. WSL's patented, world-first technology confines the laser hazard to a small area around the work, achieving a Class I classification — the only laser cleaning technology of its kind anywhere in the world.
This unlocks open-plan manufacturing, mixed-use facilities, and public-facing work such as graffiti removal and heritage restoration. If your environment includes shared or public spaces, the RHZ configuration is worth serious consideration.

The ELASER-RHZ brings full 300W cleaning capability to open-plan facilities without the safety overhead of a conventional Class IV system. Download the datasheet for complete specifications.
No Consumables, No Chemicals, No Compromise
The ELASER cleans using laser light alone. No abrasives, no chemicals, no water, no consumables of any kind — nothing to order, stock, or dispose of. The system is air-cooled, so there is no chiller, no water circuit, and no coolant infrastructure to install or maintain.
Running costs are, in practice, electricity only. Compare that with sandblasting (media purchase and disposal), chemical stripping (procurement, compliance, and effluent costs), or water-jetting (water consumption and waste handling) — the operational cost base is categorically different.
Designed, Built and Supported in Britain
Woodrow Scientific is the only UK-based laser cleaning manufacturer, founded in 2012. Every ELASER is designed, built, serviced and improved in-house. Much of the laser cleaning market is supplied by resellers rebadging third-party machines — distributors with no in-house engineering to draw on when a problem arises.
That distinction matters over the working life of a machine. With 200+ years of combined engineering experience, WSL provides genuine technical support, fast spares and bespoke engineering for non-standard requirements.
The ELASER is CE and UKCA certified, and first-class operator training is available as part of the complete offering.
Only Reduced Hazard Zone Available
The ELASER-RHZ is the only 300W laser cleaner in the world offering a reduced hazard zone configuration. Every verified competitor — including cleanLASER, P-Laser, 4JET, Netalux, Narran, Laserax, and Rocklin — operates as a conventional Class IV system, requiring the work area to be sealed off and personnel cleared before cleaning begins.
WSL's patented technology collapses the hazard zone to a small area around the work, enabling cleaning in open workshops, mixed-use facilities, and publicly accessible environments. No other 300W laser cleaner offers this.
Up to 50 m Reach
The ELASER's delivery cable extends to up to 50 m, placing it among the longest-reach portable laser cleaners available. The wheeled unit stays put while the operator brings the scanner directly to the work.
By comparison, the Rocklin MobiLase specifies 5 m, the Netalux Needle 200/300 W specifies 5.7 m, and the 4JET JETLASER lists 15 m as standard. Greater reach reduces repositioning, supports work at height or in confined spaces, and enables single-operator efficiency across large structures.
1550 nm Retina-Safe Wavelength
The ELASER operates at 1550 nm, within the retina-safe spectral band. Verified competitors — including cleanLASER, P-Laser, Narran, Netalux, Laserax, and Rocklin — all publish a wavelength of 1064 nm.
The 1550 nm wavelength is the technical foundation for WSL's reduced hazard zone capability: at this wavelength, the eye's cornea absorbs the beam before it can reach the retina. That physical property is what makes the RHZ configuration possible. No competitor uses 1550 nm in a laser cleaning machine with a reduced hazard zone configuration.
Built and Supported In-House
WSL designs, builds, services and improves every ELASER in-house. It is the only UK-based laser cleaning manufacturer. A significant portion of the 300W laser cleaning market is supplied by resellers or importers rebadging third-party machines: when something goes wrong, there is no in-house engineering to draw on.
WSL's manufacturing depth translates directly into faster spares, genuine technical support, and a product that can be improved over time. Before committing to any laser cleaning supplier, it is worth asking directly: did you manufacture this machine?

First-Class Operator Training Available
WSL provides first-class laser cleaning safety and operation training directly as the manufacturer. Buyers receive not just the machine but the knowledge and confidence to use it safely and effectively from day one. Proper operator training is strongly recommended for safe operation of any laser cleaning system — and with WSL's training available, there is no need to source third-party courses or work it out independently.
Bespoke Engineering Available
WSL's in-house engineering capability means non-standard requirements are a conversation worth having. As the manufacturer — designing, building and improving every ELASER in-house — WSL can accommodate what a reseller or importer simply cannot. If your application has requirements that fall outside the standard specification, get in touch with WSL's engineering team.
Need Automated Laser Cleaning Instead?
If your requirement is cleaning the same part type, cycle after cycle, WSL's AutoLASE is likely the better fit. Load the part and its machine-vision 3D scanning generates the clean automatically — no programming, no path-setting, no knowledge of part geometry required.
AutoLASE can also be configured with WSL's RHZ technology, making it the only automated laser cleaning system in the world that operates without an enclosure.
WSL supplies both systems and can advise on which suits your application — get in touch to discuss.
Frequently Asked Questions
Common questions about cost, performance, installation, and getting started with the ELASER 300W pulsed laser cleaning machine.
The ELASER is priced by quote — contact WSL directly for a figure based on your configuration and application. Among comparable industrial laser cleaning machines in Europe, the ELASER is the European cost leader: competitive pricing delivered through WSL's in-house manufacturing efficiencies, not by cutting quality. The more complete picture is total cost of ownership. The ELASER runs on laser light alone — zero consumables, no chemicals, no abrasives, no media disposal. Compared with sandblasting, chemical stripping or water-jetting, the ongoing running costs are dramatically lower, and minimal substrate loss means less rework over time. For most industrial operations, that calculus changes the investment conversation considerably.
Yes. Laser ablation is a proven industrial process with a well-established track record across automotive, aerospace, heritage restoration, and precision manufacturing. The mechanism is straightforward and measurable: the laser beam vaporises the contaminant layer — rust, paint, oxide, grease, mill scale — and stops at the base material, leaving the substrate intact. It is not a marginal or niche capability; it is a repeatable, controllable outcome. The ELASER demonstrates this across a broad range of surfaces and contaminants, with power tunable across 0–100% so the same machine handles everything from light oxide films on aluminium through to thick bonded coatings on structural steel. Substrate safety is a function of that tunability — dialling down power on sensitive materials is straightforward and precise.
Same platform, different laser safety class. The standard ELASER operates as a Class IV system — conventional laser cleaning that requires the work area to be appropriately controlled before operation. The ELASER-RHZ uses WSL's patented, world-first reduced hazard zone technology to operate as a Class I system, collapsing the laser hazard zone to a small area immediately around the work. This removes the requirement to seal off and evacuate the surrounding area, making it practical to clean in open workshops, mixed-use manufacturing facilities, and publicly accessible environments where conventional Class IV laser cleaning would be impractical or impossible. No other laser cleaning machine in the world offers this capability — it is WSL's patented technology. If your environment includes shared spaces, public access, or open-plan operations, the RHZ configuration is the configuration to consider.
No — on both counts. The ELASER is fully air-cooled: no water circuit, no chiller, no coolant infrastructure of any kind. It runs on a standard 110–250 VAC single-phase supply and consumes under 2,000 W. No compressor is required. The practical implication is genuine plug-in-and-clean operation: wheel the unit to the work, connect to a standard power outlet, and start cleaning. No building works, no specialist commissioning, no ongoing consumables to stock or manage. For operations that move between sites or need to clean in place, this self-contained setup is a significant operational advantage.
WSL provides first-class laser cleaning safety and operation training directly as the manufacturer. Buyers receive the knowledge and confidence to operate safely and effectively from day one. The support story goes further than training. As the only UK-based laser cleaning manufacturer — designing, building and improving every ELASER in-house since 2012 — WSL's own engineering team is the support team. That means faster spares, direct technical answers from the people who built the machine, and the genuine ability to improve or customise the system over time. A significant portion of the laser cleaning market is supplied by resellers or importers with no in-house engineering capability. When something goes wrong with a rebadged machine, the supplier cannot provide what a manufacturer can. WSL can — backed by over 200 years of combined engineering experience.
A portable laser cleaning system, combined with proper operator training, gives a service provider a genuinely differentiated commercial offering. The ELASER is a strong platform for this use case for several concrete reasons. Running costs are effectively electricity only — no consumables to purchase, stock or dispose of. One machine covers a wide range of client jobs across metals, stone, masonry and more, so a single investment supports a broad service offering. The ELASER-RHZ configuration extends that further: its reduced hazard zone enables public-facing work such as graffiti removal and heritage or monument restoration — environments that conventional Class IV laser cleaning systems cannot easily serve, giving an RHZ-equipped operator access to markets that competitors cannot reach. WSL explicitly supports buyers looking to launch a laser cleaning service, including providing first-class safety and operation training to get started on the right footing.
