The ELASER: What It Is and What Sets It Apart
The ELASER is a portable, pulsed industrial fibre laser cleaning system — a wheeled unit with a sub-3 kg handheld scanner and up to 50 m of delivery cable. It removes rust, paint, oxides, oil, and coatings by laser ablation, stopping precisely at the base material. Air-cooled and consumable-free: no water circuit, no compressor, no media.
Woodrow Scientific Limited is the only UK-based laser cleaning manufacturer, designing and building its own machines in-house since 2012. The family includes the ELASER-RHZ: the world's only reduced-hazard-zone portable laser cleaner — a Class I, patented, world-first variant no other manufacturer offers.
Laser Source Specifications
Max power: Up to 300 W — spanning the 200 W class and beyond, tunable 0–100%. Wavelength: 1550 nm (retina-safe; the technical basis for the ELASER-RHZ variant). Pulse energy: Up to 15 mJ. Pulse duration: 100 ns. Pulse repetition rate: Adjustable up to 200 kHz.
Beam Delivery and Optics
Scanner: 2-D galvanometer, 10 m/s maximum scan rate. Scan shapes are fully programmable via the GUI touchscreen, letting the operator match the cleaning pattern to the surface geometry — not just the power level.
F-Theta lenses: Interchangeable, covering a 75–500 mm working distance range. Lens-protection windows: Included and field-replaceable.
Weight, Cable, and Mobility
Delivery cable: Up to 50 m (standard configurations: 5 m and 15 m). Many comparable portable laser cleaners are limited to 5–10 m of reach — the ELASER's 50 m capability is a significant on-site advantage.
Handheld scanner: Under 3 kg. Full system: Under 50 kg on wheels. Single-operator deployment, no fixed installation required.
Supply, Cooling, and Controls
Power supply: 110–250 VAC single-phase — standard industrial supply, no three-phase infrastructure required. Power consumption: Under 2000 W. Cooling: Air-cooled; no water circuit, chiller, or compressor needed.
Interface: Ethernet + graphical touchscreen with password-protected access and per-user logins. Single-phase supply combined with air cooling makes the ELASER genuinely self-contained on site.
Certifications and Manufacture
Laser class: Class IV (standard ELASER); Class I (ELASER-RHZ — the eye-safe classification). Certifications: CE and UKCA — both marks held, covering GB and EU markets. UK buyers requiring UKCA compliance will find it confirmed here.
Manufacture: Made in Britain by Woodrow Scientific Limited. Designed, built, and supported in-house in the UK.
Pulsed Laser Cleaning: Why the Physics Protects Your Parts
At 100 ns pulse duration, the ELASER's bursts are too brief for heat to conduct into the substrate. The contaminant ablates; the base material stays at ambient temperature — no softening, no discolouration, no dimensional change on precision components.
CW lasers deliver sustained heat, which suits heavy structural descaling on robust substrates. On precision parts, thin sheet, or heritage surfaces, that continuous thermal input becomes a liability. Pulsed cleaning sidesteps the problem entirely.
With power tunable across the full 0–100% range, one machine handles light oxides on delicate surfaces through to thick coatings on heavy stock.
Portability That Performs in the Field
The ELASER's portability specs aren't a convenience claim — they're operational capability. One person, no fixed infrastructure, no site preparation. The machine comes to the work.
Up to 50 m Delivery Cable Reach
Many portable laser cleaners use 5–10 m cables, tethering the operator to the unit. At up to 50 m, the ELASER lets you move freely.
Under 50 kg, Wheeled, Fits Any Doorway
No forklift, no crane, no advance logistics. The wheeled system rolls to the job — through a standard doorway, one person, no special handling required.
110–250 VAC Single-Phase Power Supply
Plugs into a standard industrial or site supply. No three-phase infrastructure, no generator upgrade, no electrical survey before deployment.
Air-Cooled: No Chiller, No Compressor
No water circuit, no chiller, no compressor. Arrive on site, plug in, and clean. Nothing else to connect, transport, or set up.
Deploy Anywhere, Without Infrastructure
Lightweight scanner, 50 m reach, single-phase power, air-cooled. Together, these make the ELASER a genuinely deployable system — on-site, in the field, across multiple locations.
Applications Suited to 200W Pulsed Laser Cleaning
Six use cases where pulsed power at this tier genuinely excels: substrate-sensitive precision work, on-site industrial maintenance, and deployable service operations. If your application is here, the ELASER is built for it.
Automotive: Pre-Weld Prep and Rust Removal
Pulsed precision protects thin sheet metal that continuous-wave power would risk distorting.
Industrial Maintenance: On-Site Plant and Equipment
Nothing to mask off, no media to clear — 50 m cable covers the work.
Heritage and Restoration: Stone, Metal, and Masonry
Minimal heat transfer to the substrate makes pulsed the only safe mode for irreplaceable surfaces.
Injection Moulding: Clean Moulds In Place
Pulsed precision strips release agents from tool steel with zero thermal damage, no disassembly.
Laser Cleaning Services: One Machine, Any Site
Wheeled, sub-50 kg, single-phase power: a portable foundation for a multi-site service business.
Aerospace: Precision Surface Prep to Tight Tolerances
The beam stops at the base material, leaving surface metallurgy and dimensions fully intact.

ELASER-RHZ: Eye-Safe Laser Cleaning, Anywhere You Work
Conventional Class IV laser cleaning requires the surrounding area to be sealed off and evacuated before work can start — a real operational barrier in open-plan facilities, mixed-use workshops, or any setting where surrounding operations cannot simply stop.
The ELASER-RHZ changes that entirely. WSL's patented technology collapses the laser hazard zone to a small area around the work itself — the world's only portable laser cleaner of its kind. Clean in open manufacturing facilities, mixed-use workshops, and public-facing settings without sealing off the area or shutting down surrounding operations.
The Only UK Laser Cleaning Manufacturer: Built Here, Backed Here
Woodrow Scientific Limited is the only UK-based laser cleaning manufacturer. Founded in 2012, WSL designs, builds, services, and improves every machine in-house, backed by 200+ years of combined engineering experience — not a reseller.
A significant portion of laser cleaners sold in the UK are imported and rebadged. Resellers cannot offer in-house engineering support, cannot genuinely improve the product, and depend on overseas supply chains for parts.
CE and UKCA certified for GB and EU markets. Operator training includes password-protected access and per-user tracking. Bespoke engineering available — get in touch.
Electricity Is the Only Running Cost
Abrasive blasting and chemical stripping carry a recurring consumable spend: media to replenish, chemicals to buy, waste to dispose of. The ELASER has none of that. Laser light alone does the cleaning — no abrasives, no chemicals, no consumables on any regular cycle.
Over a working life measured in years, that structural difference in running cost is significant. The energy bill is the bill — nothing else.
No Chiller, No Coolant, No Circuit
Water-cooled laser cleaners carry costs that rarely appear in the headline price: a chiller unit to purchase, a water circuit to maintain, and ongoing coolant expenses. The ELASER is air-cooled — there is no water circuit, no chiller, and no coolant cost at any point.
That is a genuine operational saving over the machine's working life, not just a setup convenience.
Cleaner Surfaces, Lower Rework Cost
Sandblasting and wire brushing routinely cause surface damage — pitting, material loss, dimensional change — that requires correction before a part can proceed. That correction is a real labour and materials cost on every job.
The ELASER's pulsed beam stops at the base material, leaving the substrate intact. Parts typically require no post-cleaning correction, which reduces time, waste, and total cost per part.
Built In-House, Priced Competitively
The ELASER is the European cost leader among comparable industrial laser cleaning machines — the most competitive upfront pricing in its class, achieved through WSL's in-house manufacturing efficiencies rather than by compromising on quality.
Imported and rebadged machines carry a reseller margin that inflates the price without adding value. WSL designs, builds, and supports every machine itself — so that margin does not exist, and the saving passes directly to the buyer.

Need High-Volume Throughput? Meet AutoLASE.
AutoLASE is WSL's automated laser cleaning system: the cleaning head sits on an articulated robotic arm. Load a part and machine vision scans it, builds a 3D map, and generates the clean automatically. No programming, no path-setting, no technical skill required. It is the right tool when cleaning is repetitive, high-volume, or needs to be taken out of manual labour entirely.
AutoLASE is also available with the RHZ eye-safe upgrade — making it the only automated laser cleaner in the world that can operate without an enclosure. If your application spans portable and production-scale cleaning, speak to the WSL team.
Frequently Asked Questions
The questions buyers most commonly ask before enquiring about the ELASER, answered directly.
A wide range of contaminants, including rust, oxides, mill scale, paint, powder coating, lacquer, primer, oil and grease, carbon and soot, mould, graffiti, adhesives and residues, tarnish, weld discolouration, and release agents. If it sits on top of a base material, pulsed laser ablation will remove it. The ELASER's fully tunable power (0–100%) means the same machine handles light surface tarnish and heavy mill scale — no separate tool, no separate process.
Metals — including steel, carbon steel, aluminium alloys, cast iron, copper, brass, bronze, titanium, and galvanised — and non-metals including stone, concrete, brick, and masonry. Because laser power is tunable from 0–100%, one machine handles both precision-sensitive surfaces and robust industrial substrates. Fixed-power machines force a compromise; the ELASER does not.
Pulsed laser cleaning delivers short, high-peak-power bursts rather than a sustained beam. The ELASER fires 100 ns pulses with up to 15 mJ pulse energy — each burst is brief enough that heat cannot conduct meaningfully into the substrate before the pulse ends. The contaminant ablates; the base material stays at ambient temperature. That is why pulsed is the right choice for precision components, thin sheet metal, and any surface where thermal damage is a real risk. Continuous wave (CW) delivers sustained energy, which suits heavy structural cleaning but introduces thermal risk on delicate or thin substrates. If you have already specified pulsed, your instinct is correct — the ELASER delivers exactly that.
Yes, completely. The ELASER is designed for single-operator deployment with no additional infrastructure or assistance required. The wheeled system unit weighs under 50 kg and moves through a standard doorway; the handheld scanner weighs under 3 kg. Delivery cable reaches up to 50 m, so the unit stays put while the operator moves freely around the work. Power is 110–250 VAC single-phase — a standard industrial or site supply. The system is air-cooled, so there is no water circuit, chiller, or compressor to transport or connect. Arrive, plug in, and clean.
The ELASER-RHZ is the eye-safe variant of the ELASER, using WSL's patented technology to collapse the laser hazard zone to a small area around the work itself. Conventional Class IV laser cleaning requires the surrounding area to be sealed off and evacuated before work can start. The ELASER-RHZ removes that barrier entirely — cleaning can proceed in open workshops, mixed-use facilities, and public-facing environments without shutting down surrounding operations. It is the world's only portable laser cleaner of its kind. If your operating environment is an open-plan facility, a shared workspace, or a publicly accessible setting, the ELASER-RHZ is the right choice. If you have a dedicated, controlled cleaning area, the standard ELASER (Class IV) is the appropriate fit. WSL provides full training for both variants.
Yes — the ELASER holds both CE and UKCA certification. CE covers the EU market; UKCA covers Great Britain. Both marks confirm the machine meets the relevant conformity requirements for placing on those markets, giving buyers in the UK and across Europe a straightforward compliance position. For UK buyers, UKCA is the mandatory conformity marking for goods placed on the GB market following the UK's departure from the EU — the ELASER carries it as standard.
Yes, and WSL provides it. Every ELASER comes with access to first-class laser cleaning safety and operation training delivered by WSL directly — the people who designed and built the machine. Training is a professional standard for laser operation, not a hurdle. The ELASER also has safety and accountability built into the hardware itself: password-protected access and per-user logins with usage tracking mean only trained, authorised operators can run the system, and every session is logged.
Pricing is by quote — contact the WSL team to discuss your application and they will provide a tailored figure. The right configuration depends on factors including power level, variant (standard ELASER or ELASER-RHZ), and cable length, so pricing is matched to your specific situation rather than taken from a fixed list. The ELASER is competitively priced as the European cost leader in its class. Get in touch and the team will take it from there.
