Abstract

This review makes an attempt to analyze the experiment and qualitative theoretical results related to fundamental photochemical and photophysical processes in laser machining of glasses and glass-ceramics, on the one hand, and phase-change memory alloys on the other hand, where a controllable laser exposure can locally change the properties of a material, e.g., its chemical solubility and transmittance in the visible and IR spectral ranges. In some cases, the process may be reversed, either thermally or by appropriately choosing the parameters of the laser exposure..
