Description

technical field [0001] The invention relates to the field of laser removal processing of hard materials, in particular to a 1064nm laser. Background technique [0002] Hard raw materials need to be removed and processed before they can be used as products and applied in corresponding fields. Hard materials need to be cut on different sides during processing. At present, most of the processing methods for hard 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, which swing to a certain extent when they run fast, resulting in high precision. Low, the moving parts are easy to raise the dust generated when cutting super-hard materials, the pollution is large, and the noise of mechanical cutting is also large. [0003] With the continuous maturity of laser generators, the use of lasers in cutting is becoming more and more extensive. The lase...

AI Technical Summary

Problems solved by technology

However, compared with lower power lasers, high power lasers generate a lot of heat due to their pumping, and the thermal lens generated by too much heat can cause the resonator to be unstable, resulting in poor beam quality

Many hard materials are extremely expensive and fragile, so the requirements for processing yield are extremely high

However, the infrared lasers currently on the market are either not powerful enough, or the beam quality of the enough power is not enough, and the yield rate of the processed parts is very 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
