Problems solved by technology
The existing laser spot roundness adjustment method is that the same two beams of pump light are transmitted or refracted from different directions through different lenses, mirrors, etc., and finally focused with the same spot size. If the spot position is misplaced, the final obtained The roundness of the light spot may not be round. To meet the requirements of the processing technology, it is necessary to repeatedly debug the misalignment of the light spot, which is difficult to debug.

Abstract
The invention discloses a method for optimizing laser spot roundness. The method comprises the steps: arranging a first convex lens between a first pump light source and a laser crystal; arranging a second convex lens between the second pump light source and the laser crystal; setting the focal length ratio of the first convex lens to the second convex lens to be within the range of 0.5-0.8; enabling the pump light emitted by the first pump light source to pass through the first convex lens and then reach the laser crystal to generate small light spots; enabling the pump light emitted by the second pump light source to pass through the second convex lens and then reach the laser crystal to generate a large light spot, wherein the large light spot comprises a small light spot. The inventionfurther discloses a system for optimizing the laser spot roundness. According to the method and the system, the generated large light spots include the small light spots, so that the cross overlapping phenomenon is avoided, the roundness of the light spots is ensured, and the debugging difficulty of the roundness of the light spots is reduced.
Description
technical field [0001] The invention relates to the technical field of lasers, in particular to an optimization method and an optimization system for the circularity of a laser spot. Background technique [0002] Solid-state lasers have the advantages of high brightness, high efficiency, compact structure, stable performance, long life and full solidification, and have important applications in materials processing and other fields. [0003] Due to the different processing technology requirements of different workpieces, there are more requirements for the laser spot. For example, the roundness of the circular spot needs to be more optimized and the energy distribution is more uniform. Therefore, it is necessary to adjust the roundness of the laser spot through an optimization method to make it better. Meet different process requirements. The existing laser spot roundness adjustment method is that the same two beams of pump light are transmitted or refracted from different ...
