Pulsed Laser Cleaning Machines
Pulsed fibre laser cleaners use high peak power pulses to ablate contamination without sustained heat delivery to the base material. ApexLase ARC series machines are powered by JPT MOPA — the professional choice for restoration, precision engineering, automotive, and industrial surface preparation across the UK.
How Pulsed Laser Cleaning Works
Pulsed cleaning fires discrete bursts of laser energy. Each pulse raises the contaminant's surface temperature almost instantaneously, causing ablation (vapourisation and ejection) before the heat transfers into the substrate. The result: the contamination is removed while the base material remains at or near ambient temperature.
High Peak Power
JPT MOPA architecture delivers peak powers far exceeding average output — enabling aggressive ablation even at moderate average wattage settings.
Adjustable Pulse Duration
Pulse width from nanoseconds to microseconds is independently tunable. Short pulses are more aggressive; longer pulses allow controlled heat input for specialist applications.
Selective Ablation
Contaminants have different absorption coefficients to base metals. Correctly set, pulsed lasers remove the contamination layer while leaving the substrate largely unaffected.

Frequently Asked Questions
What is a pulsed laser cleaning machine?
A pulsed laser cleaner fires short, intense bursts of laser energy rather than a continuous beam. Each pulse delivers high peak power in a fraction of a millisecond. This allows the contaminant to absorb and eject the energy before it transfers as heat to the base material — the key property that makes pulsed cleaning safe for thin metals, historic materials, and complex surfaces.
What is JPT MOPA and why does it matter?
JPT MOPA (Master Oscillator Power Amplifier) is a fibre laser architecture that gives precise, independent control of pulse duration, repetition rate, and peak power. This flexibility is essential for matching cleaning parameters to specific contamination types and substrates. JPT is one of the leading fibre laser source manufacturers globally and is used in professional industrial systems.
How powerful a pulsed laser do I need?
300W is suitable for restoration, light rust removal, mould cleaning, and portable applications. 500W handles heavier rust and thicker coatings with more throughput. 1000W pulsed is for demanding industrial batch cleaning where throughput is critical but substrate protection still matters. A detailed discussion of your application will narrow this down quickly.
Is a pulsed laser cleaner suitable for painted steel cars?
Yes — pulsed laser cleaning is widely used for automotive restoration, including rust and paint removal from body panels and structural components. The ability to control pulse energy and frequency means the laser can be set to remove paint or rust without marking the base metal.
