2-kW continuous wave laser demonstrator simulation using incoherent beam combining of laser diode stacks

In this paper, the simulation of a 2-kW laser demonstrator using a free-space incoherent beam combining based on two laser diodes stacks at 980 nm is presented. The implementation of the simulations is done in Optic Studio Zemax software. The goal of this work is to design and validate the feasibility of the construction of an experimental laser demonstrator in a laboratory for rapid prototyping of high-power laser sources. The simulation results are characterized using power density at a detector, beam parameter product, and spot size as descriptors.
