Abstract

The invention relates to a processing method of matched crystals used in a laser Q-switching device. The processing method comprises the following steps: 1) cutting a crystal strip; 2) conventionally molding an upper surface and a lower surface of the crystal strip; 3) respectively plating a metal electrode on the upper surface and the lower surface of the crystal strip; 4) conventionally molding a left end face and a right end face of the crystal strip, placing the end faces on a plate, and conventionally molding a front surface and a rear surface of the crystal strip; 5) conventionally polishing the front surface and the rear surface of the crystal strip; 6) carrying out film coating operation on the front surface and the rear surface of the crystal strip; and 7) cutting the crystal strip into actually required size. The invention also discloses another two similar processes. The three methods can keep the lateral verticality of all processed crystals consistent, and the optical direction angles of all processed crystals consistent, prevent differences among monolithic crystals brought by prior processing processes, improve the matching rate of crystals, as well as improve the rate of finished products and efficiency, and reduce cost.

Description

technical field [0001] The invention relates to the processing of paired crystals in laser components, in particular to a processing method of paired crystals used in laser Q-switching devices. Background technique [0002] Electro-optic Q-switching technology uses the electro-optic effect of the crystal to apply a voltage on the crystal to change the refractive index of the crystal to change the polarization state of the laser passing through the crystal. When used in conjunction with a polarizer, it can realize the role of an optical switch inside the laser. Using electro-optic Q-switching technology, the width of each pulse of pulsed laser can be compressed and the peak power of each pulse can be increased. [0003] Using a biaxial electro-optic crystal as an electro-optic Q-switching device needs to overcome the natural birefringence effect of the biaxial crystal itself. The current method is to use two electro-optic crystals, with the light transmission direction as the...
