Laser energy is focused onto the part and steered through the cleaning area using a galvanometer. The high energy density beam reacts with the surface to remove the unwanted coating or layer.
Laser cleaning is important to many industries, including aerospace, automotive, medical—and more. Applications include:
Laser cleaning processes work best when the unwanted layer has a high absorption rate within the laser’s wavelength range and the underlying substrate is reflective within the same range. This relative absorption difference causes the unwanted material to heat up quickly and ablate from the surface—leaving the substrate unaffected. A fume extraction system then removes the airborne material in a clean and controlled manner.
Though near-infrared wavelengths are commonly used for laser cleaning, you might require different wavelengths depending on the absorption properties of your material.
