Laser simulation at the Air Force Research Laboratory

The physics of high brightness, high-power lasers present a variety of challenges with respect to simulation. The Air Force Research Laboratory is developing high-fidelity models for Yb-doped, Tm-doped, and Raman fiber amplifiers, hollow-core optical fiber gas lasers, and diode pumped alkali lasers. The approach to simulation and the physics specific to each laser technology are described, along with highlights of results, and relevant modeling considerations and limitations.
