Abstract

The invention discloses a fiber laser device and a cutting method for cutting sapphire glass. According to the fiber laser device, a single-mode continuous pulse fiber laser for cutting a mouth is arranged at an emitting outlet of the laser device. The cutting method includes the following steps that firstly, the sapphire glass with the surface coated by absorbing agents is placed on a jig, and the height of a cutting head is debugged according to the thickness of the sapphire glass; secondly, the pressure of cutting gas is debugged; thirdly, the focusing height, the speed, the pulse width and the power of the device are debugged; fourthly, laser beams of a single-mode continuous pulse are focused in a high power mode and vertically emitted to the surface of a sapphire glass sample to be processed; fifthly, the sapphire glass is cut. With the cutting method flaws of processed products and the processing cost can be greatly reduced. Produced sapphires are high in electrical performance, wear-resistant and free of sticking of films and other coatings.

Description

technical field [0001] The invention belongs to the field of glass cutting by laser equipment, and more specifically relates to an optical fiber laser equipment and a cutting method for cutting sapphire glass. Background technique [0002] Sapphire glass is resistant to scratches, abrasions, and corrosion, and has long been installed on world-class brand-name watches. The advantages compared with other glasses have long been understood by many people, but due to the price of the material itself and the difficulty in processing, it has not been widely used. At present, the material cost of sapphire glass has dropped from 30 times that of ordinary glass to less than 10 times. If the difficulty of processing and production can be made a breakthrough, the processing cost can be greatly reduced. The days when sapphire glass is widely used will be Not far away. [0003] In recent years, laser technology has made great progress, and breakthroughs have been made in conventional pr...
