Paper Abstract

A model for calculation of stored energy and heat source assessment in a laser crystal has been developed. We report that in a pulsed laser amplifier using Yb:YAG slabs at low temperature with ASE suppressing MLD absorptive layer, 58% of the pump energy is deposited as heat and has to be cooled, while only 11% of the pump energy is converted into heat inside the pumped part of the Yb:YAG crystal itself.
