Abstract

The invention provides a point changing device and method for a nonlinear crystal in a laser. The point changing device comprises a temperature control console which is in contact with a first mounting plane and is used for placing the nonlinear crystal, a first elastic piece which is in contact with the first side surface and is used for limiting the nonlinear crystal to move on the temperature control console, a linear driving device which is in contact with the second side surface and is used for pushing the nonlinear crystal to move, and a controller which is connected with the linear driving device and used for controlling the linear driving device to move. The direction in which the linear driving device pushes the crystals to move is parallel to the light transmission plane of the first crystal and the light transmission plane of the second crystal. The device has the advantages of being simple in structure, convenient to operate and beneficial to large-scale industrial production and manufacturing of the laser.

Description

technical field [0001] The invention relates to the technical field of frequency doubling / combining / difference frequency of lasers, in particular to a point changing device and method for nonlinear crystals in lasers. Background technique [0002] Lasers have developed rapidly in precision processing applications such as 3C electronics, automobile manufacturing, and medical device processing. Lasers with different wavelengths have different processing effects on different processing materials such as glass, ceramics, PCB boards, copper boards, and plastics (PPS, PPA). Therefore, in the field of industrial lasers, the technology of using fundamental frequency lasers to pass through nonlinear crystals to obtain different wavelengths (frequency doubling / combining frequency / difference frequency) has been widely used in recent years. At the same time, the complex and changeable industrial application scenarios have put forward higher requirements for the long-term and stable out...
