532nm parallel connection beam combination laser

Abstract

The invention discloses a 532nm parallel connection beam combination laser, comprising two Z-shaped resonant cavities which are arranged in parallel, each Z-shaped resonant cavity comprises an acousto-optic Q switch, a 1064nm laser module and a resonant lens set which are adjacently arranged, the resonant lens set is used for converting 1064nm light into 532nm light, and a wave plate is arranged at the output end of each Z-shaped resonant cavity; and a laser beam combination mirror set is arranged at one side of the output ends of the two Z-shaped resonant cavities. The 532nm parallel connection beam combination laser provided by the invention guarantees relatively high beam quality while laser power is doubled by virtue of laser beam combination, so that cutting precision on a superhard material is improved.

Description

technical field [0001] The invention relates to laser cutting processing of superhard materials, in particular to a 532nm parallel beam laser. Background technique [0002] Original superhard materials (such as natural diamonds) need to be processed before they can be used as products and applied in jewelry or industrial fields. Different surfaces need to be cut during processing of superhard materials. At present, most of the processing methods for superhard materials are mechanical cutting, manual grinding and polishing, etc., and the operation is complicated. Among them, mechanical cutting requires high-speed running parts (such as saw discs), and there is a certain degree of swing during fast running, resulting in accurate The degree of precision is low, and the moving parts are easy to raise the dust generated when cutting super-hard materials, resulting in heavy pollution, and the noise of mechanical cutting is also large. [0003] With the continuous maturity of las...

AI Technical Summary

Problems solved by technology

The green lasers on the market are either not powerful enough, or the quality of the beam with enough power is not enough, and the yield rate of the processed parts is very low.

Moreover, there are certain differences in the structure of lasers with different powers, and the change of the power of the laser module is not linear, which is difficult to adjust. As a result, in actual use, the output power range of a single laser is narrow and the applicability is low.

In addition, the current lasers are large in size, and the beam contains more light of different wavelengths, and the beam quality is low, which cannot be applied to the field of precision processing of high-end superhard materials
