Abstract
Solid-state lasers are pivotal in a wide range of defense applications. In this study, we present a comprehensive simulation model for advancing solid-state laser capabilities, focusing on Ho3+:YAG for SWIR generation. This versatile model integrates different optical components, including mirrors and laser crystals, allowing flexible resonator and free-space modeling. It employs a multi-physics approach utilizing a beam propagation method for simulating laser fields and 3D temperature and stress distributions based on finite difference methods. The combined model allows for the optimization of solid-state laser systems for power output, efficiency, and beam quality.
