Problems solved by technology

[0003] In order to increase the power of frequency-doubled light, a common method is to use strong focusing to increase the power of fundamental-frequency light irradiated on the frequency-doubled crystal. This method greatly increases the heat per unit area that the crystal surface bears when the laser enters the frequency-doubled crystal. , so that the frequency doubling crystal is easily damaged in the process of frequency doubling, forming crystal dead spots, thus destroying the stability of frequency doubling and shortening the service life of the crystal

Abstract

The invention discloses a frequency doubling crystal holder in a high power solid laser. The frequency doubling crystal holder comprises a base and a frequency doubling crystal fixing block. The base comprises a bottom plate which is horizontally arranged. The upper surface of the bottom plate is vertically connected with at least three guide columns which are not in the same row. A support plate parallel to the bottom plate is arranged above the bottom plate. The support plate is in slidable sleeve joint with the guide columns through guide sleeves. The upper surface of the bottom plate is fixedly connected with two brackets. A rotating shaft parallel to the support plate is rotationally arranged between two brackets. The rotating shaft is located between the bottom plate and the support plate. At least one cam is fixedly arranged on the rotating shaft. The cam abuts against the bottom of the support plate. One end of the rotating shaft is connected with a drive motor. The frequency doubling crystal fixing block is fixedly connected with the upper surface of the support plate. According to the invention, relative movement of a frequency doubling crystal and the light path of a base frequency light is realized; the exposure time of the base frequency light on the same point of the frequency doubling crystal is reduced; and the service life of the frequency doubling crystal is prolonged.

Description

technical field [0001] The invention relates to a frequency doubling crystal support in a laser, in particular to a frequency doubling crystal support in a high-power solid-state laser. Background technique [0002] After the fundamental frequency light excited by the high-power solid-state laser penetrates the frequency doubling crystal, the frequency doubling light is obtained. The frequency and power of the frequency doubling light are lower than the fundamental frequency light. The quality and power of the frequency doubling light depend on the properties of the frequency doubling crystal And control over the method of using frequency doubling crystals. The properties of the frequency doubling crystal are determined by the crystal itself and are not affected by the outside world. Before there is a new higher performance frequency doubling crystal, improving and optimizing the external environment and usage methods of the frequency doubling crystal has become the key to i...
