Abstract

The pumping cavity we propose for solar-pumped lasers consists of a compound parabolic concentrator (CPC) and a conventional cone-shaped cavity. We applied ray tracing and FEM simulation in designing the cavity. Simulation results suggest that the cavity increases absorption efficiency 1.2 times over the conventional cone-shaped cavity and decreases the standard deviation of absorption density distribution by 33% and thermal stress by 19% over the conventional. Our evaluation of the cavity in lasing experiments realized 80 W in stable laser output.
