The difference between continuous laser cleaning machine and pulse laser cleaning machine

By 创始人 on

Continuous laser cleaning machines and pulsed laser cleaning machines are the two main types of laser cleaning technology. They are primarily used to remove surface contaminants and are widely used in industrial manufacturing, automotive repair, and cultural heritage preservation. The key difference between the two lies in the laser output mode: Continuous lasers provide a stable, continuous beam suitable for rapid cleaning of large areas; pulsed lasers deliver high-energy, short pulses, emphasizing precise control and minimal thermal damage.



Continuous Laser Cleaner (CW)Pulsed laser cleaning machine (Pulsed)
How it worksContinuous beam heat transfer vaporizes pollutantsShort pulses of energy instantly strip away contaminants
Laser outputStable and continuous, wavelength 1064nmHigh energy pulse, pulse width ns-μs, frequency kHz-MHz
Power range

500-2000W

100-1000W (peak kW)
Cleaning efficiencyHigh (large area, m/min level)Medium to high (precision, cm/s level)
Heat-affected zoneLarger (0.5-1mm, may be deformed)Extremely small (<0.2mm, almost no damage)
Application ScenarioPlastic/large area cleaning (such as car shells, pipes)Metal/precision cleaning (such as electronic boards, cultural relics)
AdvantageFast speed, low cost and simple operationPrecise, damage-free, and multi-material compatible
ShortcomingLarge and uneven thermal damageSlow, costly, and complex
Development TrendsHigh-power automationNanosecond pulse, multifunctional integration
