Abstract

In this paper, an integrated semiconductor disc laser is designed with the integrated design of the laser source, optical system and heat sink system. The 808 nm VCSEL array is used as the pump source and the Nd:YVO₄ crystal is used as the gain medium. The pump source and the gain medium are placed on the same substrate, and both of them share a common cooling system. The collimating optical system of the VCSEL array and the reflective focusing optical system are designed using ZEMAX software, and the focusing spot radius is 1.3 mm, which matches with the theoretical calculation of the crystal pump spot size. The feasibility of integrating the pump source and gain medium in a same cooling system is analyzed using Flow Simulation and ANSYS software, and an air-cooled thermal system is designed by comparing the thermal simulation results of the water-cooling method for verification. Realization of opticalmechanical thermal integration design.
