Embodiment 1

[0029] Embodiment one: see figure 2 As shown, a transparent glass processing device is composed of a green laser, a scanning galvanometer, and a focusing lens. See figure 1 , the green laser is mainly composed of a pulse seed fiber laser with an output wavelength between 1020 nm and 1090 nm, a multi-stage or single-stage fiber amplifier, a collimator, and a frequency doubling device. The output light of the pulse seed fiber laser passes through an optical fiber After the amplifier is amplified, it is collimated by the collimator and then frequency multiplied by the frequency doubling device to output green light; the green light is focused on the position of the transparent glass to be processed by the focusing lens after passing through the scanning galvanometer.

Abstract

The invention discloses a transparent glass machining method and device, and provides an optical fiber laser device with wavelength of 1020 nanometers to 1090 nanometers. After energy amplification is conducted on laser beams output by the optical fiber laser device through an optical fiber amplifier, optical frequency multiplication is conducted to obtain output green light, the output green light has pulse repetition frequency of larger than 100 KHz, pulse width of smaller than 10 ns and pulse peak power of larger than 15 KW. Energy amplification is conducted on the laser beams output by the optical fiber laser device only through the optical amplifier; the green light is focused on a to-be-machined position of transparent glass, and the transparent glass is machined by moving the focusing position. The transparent glass machining method and device are quite stable in laser output, ensure the glass machining accuracy, can be used for machining various complex patterns and meanwhile increase the machining speed.

Description

technical field [0001] The invention relates to a glass processing method, in particular to a laser processing method for glass. Background technique [0002] Glass has become an indispensable part of people's daily life. With the development of economy, the demand for glass products is increasing day by day. In the glass production industry, glass processing is a very important link. [0003] Generally speaking, glass processing (cold processing) mainly includes polishing, cutting, drilling, engraving, edging, etc. In order to achieve the above-mentioned glass processing in an industrialized manner, the processing methods used in the prior art mainly include mechanical processing methods, chemical processing methods (mainly used for polishing and etching), and high-pressure water jet processing methods (mainly used for cutting and drilling) and laser processing methods. Among them, the laser processing method is far superior to other methods in terms of processing speed ...
