Laser ablation - Wikipedia

Laser ablation of an asteroid-like sample.. Laser ablation or photoablation (also called laser blasting [1] [2] [3]) is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam.. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates..
