Abstract

In order to investigate the impact of the resonator type on the beam quality of a solid-state laser, a diode pump module was built using Nd:YAG as the gain medium. A basic resonator, measuring 185mm in length, was then assembled with two different types of mirrors. There are five types of mirror fitting modes: flat mirror with flat mirror, flat mirror with concave mirror with a curvature radius of 4000mm, flat mirror with concave mirror with a curvature radius of 3800mm, concave mirror with a curvature radius of 2800mm with convex mirror with a curvature radius of 3000mm, and concave mirror with a curvature radius of 2600mm with convex mirror with a curvature radius of 3000mm. To determine the correlation between the peak power of the laser output and the beam quality of various resonators, the peak power and spot size were measured, and the M2 factor was calculated and analyzed.
