Paper Abstract

In conventional cooling operation, thermal effects and stress distribution in slabs of solid-state laser are presented by many workers, it is different with that in the solid state heat capacity laser. In this paper, the transient temperature and stress distribution in Xeon flash lamps pumped slabs for single-shot and repetitively pulsed operations will be produced in the heat capacity operation. A high speed CCD camera was used to set up an experiment system to measure the interference fringes, from these fringes' changes, the extension of the slab due to the stress and thermal expansion can be obtained. Since dielectric materials are inherently several factors stronger in compression than in tension, this temperature reversal in heat capacity operation increases the inherent fracture limit of the system and allows a heat capacity operated laser to be pumped much harder than a conventionally operated slab laser.
