17 May 2018 Solid-state laser medium temperature distribution control under lasing condition

Longitudinal temperature distribution at the surface of the end-pumped Nd:YAG laser crystal was measured using tiny piezoelectric crystals as the temperature sensors. Temperature of each sensor was determined directly by measuring the frequency of its piezoelectric resonance that was noncontactly excited by probe ac electric field. Crystal sensors are transparent to the scattered radiation and can have very small size.
