What is Laser Cleaning and How it Works?

Laser cleaning is an innovative surface cleaning technology that uses high-powered laser beams to remove contaminants, coatings, and impurities from various surfaces without damaging the underlying material. Here's an overview of how it works, its benefits, and industrial applications:

Laser cleaning utilizes pulsed laser beams to target and remove unwanted materials from surfaces. The process works as follows:

• Nanosecond-length pulses of laser light are directed at the surface to be cleaned

• When the laser light interacts with contaminants that absorb it, the contaminants either vaporize into gas or are ejected from the surface due to the pressure

• By carefully controlling laser settings, contaminants can be removed down to the bare metal without damaging the underlying surface

The laser parameters like wavelength, pulse energy, and beam shape are precisely tuned to selectively remove contaminants while staying below the ablation threshold of the base material.

Key Benefits of Laser Cleaning

Laser cleaning offers several advantages over traditional cleaning methods:

Eco-Friendly Technology

• No chemical waste or hazardous materials produced

• Low environmental footprint with no disposal issues

• Compliant with environmental regulations

Cost and Energy Efficient
