Laser Surface Removal

Laser remediation has been used in various industries throughout military, medical and consumer electronics. This fast and efficient cleaning process without secondary waste make this cleaning technique the undisputed choice.

How does it work?

A high powered Nd:YAG laser is pulsed at varying frequencies and high energy. The pulsed energy is delivered through a fiber optic cable guide to a handheld end effector where a combination of specialized optics and steering electronics focus a rasterized beam up to 80mm wide onto a surface. The energy is readily absorbed by surface oxides, paints, rust, and or other chemicals and instantly becomes vaporized leaving only the base material in an as-found or an as-built state.

Does it damage the underlying surface?

The substrate material, unlike the target contaminant or coating, normally does not absorb, but rather reflects the  energy. Once a reflective substrate material has been reached, the laser cleaning process automatically stops. Due to typically high reflection factors, metallic surfaces are especially suitable for laser cleaning. Precise laser beam adjustments enable treatment without mechanical or thermal damage to base substrates.

Where does the removed coating go once it has been laser treated?

Immediately following the laser cleaning process, the surface material is instantly debonded and vaporized into a combination of gas and superfine particulates.  Our end effector has an integrated suction system that vacuums any airborne gas or particulates through a 3-stage HEPA filtering system. Laser cleaning … a dust-free process with no secondary waste.

What and where can laser be used?

Laser applications vary and can replace most cleaning methods. A manual or automated approach can be used to deliver the optical head to the target area. The area of interest will need to have line-of sight for the laser energy to impact the surface.

Components which have intricate details, reliefs, or items with corrosion that need to be cleaned but without leaving impinged effects on the base material are ideal candidates for laser cleaning. These items can also include structures showing forms of degradation through pitting or cracking.

Environments that need critical or absolute control of all contaminants whether introduced or from the removed materials. This could be space related for confined spaced applications or stringent safety environment protocols on airborne waste or surrounding areas.

One area that has received significant interest is in the area of radiological decontamination where laser cleaning can achieve aggressive reductions in radiation used to meet free-release equipment without any secondary byproduct or waste.
