Abstract

Temperature variations of an Er:YAG laser crystal during optical pumping with varying flashlamp pulse duration and spectral composition have been determined by utilizing temperature dependence of a cw argon laser line absorption. Time-resolved measurements of crystal gain at 2.94 micrometer have also been performed for the same set of pumping conditions. Additionally, temperature and gain profiles inside the laser rod have been determined owing to good spatial resolution of the implemented temperature measurement method.
