Continuous Laser Cleaning Machine VS Pulsed Laser Cleaning Machine

Comparison Items	Pulsed Laser Cleaning Machine	Continuous Laser Cleaning Machine
Working Principle	Emits short-pulsed laser beams, using high peak power to impact the target surface, making impurities or coatings instantly vaporize or peel off. Relies on instantaneous temperature gradients and thermal stress to remove contaminants, enabling “cold ablation”.	Emits continuous laser beams, continuously heating the object surface through constant laser energy, causing dirt to vaporize or be removed through chemical reactions.
Energy Output Characteristics	Energy is concentrated and released in a short time, with high peak power; pulse width is usually in the nanosecond to microsecond range, and frequency is adjustable.	Stable and continuous energy output with higher average power; no concept of peak power.
Average Power Range	Typically 100W-3000W	Typically 1000W-3000W
Cleaning Efficiency	Processing speed is usually slower	Processing speed is usually faster
Heat-Affected Zone	Smaller	Larger
Cleaning Effect	Can accurately remove contaminants, less likely to damage the substrate, and avoid laser lines or color differences.	Cleaning effect is relatively mild, effective on rough surfaces but easily causes micro-melting and other damages to heat-sensitive materials.
Suitable Materials	Suitable for heat-sensitive, highly reflective materials or those requiring high-precision processing, such as aluminum alloys, titanium alloys, and semiconductor wafers.	More suitable for heat-insensitive materials like carbon steel and ship plates.
Application Scenarios	Mostly used in fields with high cleaning quality requirements, such as automobile manufacturing, aerospace, and semiconductor processing, e.g., cleaning of tire molds and engine blades.	Often used in large-area cleaning scenarios like large steel structures, high-speed rail rails, and building materials.
Equipment Cost	Usually higher	Relatively lower
