laseravausta
Laseravausta is a Finnish term used to describe the removal of material from a solid surface by irradiation with a laser. In many contexts it corresponds to laser ablation, the rapid transformation of laser energy into heat, mechanical stress, and phase changes that eject material. The exact mechanism depends on the laser wavelength, pulse duration, energy, and the properties of the target, and can involve photothermal melting and vaporization, photomechanical spallation, or photochemical decomposition.
The methods rely on delivering energy with focused light to a precise spot. Short-pulse lasers, such as
Advantages of laseravausta include non-contact processing, high precision, and the ability to process complex geometries without
