Thermal analysis of transmissive elements in high-average-power laser beam delivery systems

摘要

We describe a computer code that aids in the thermal, structural, and optical analysis of laser optical systems. Inputs to the computer model include energy absorption by coatings and substrates, thermal diffusion, expansion, and heat removal parameters. The program performs steady-state thermal and structural analyses based on geometrical ray traces through the optical system. We show examples to illustrate how this capability can assist in the optical system design process.
