Monitoring the Heat of a Material during the Laser Formation of Defects

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

Results are presented from studying the role of material heating as defects form under conditions of the multiple filamentation of repeated laser pulses in lithium fluoride crystals. A way of monitoring local heating at the sites of light filament transmission is proposed, based on an analysis of the ratio of intensities of absorption bands of simple and aggregate color centers in the spectra of irradiated crystals.
