Optical lens mounting device and laser

The utility model provides an optical lens mounting device and a laser, the mounting device comprises a laser base and one or more gaskets, and an optical lens is carried on the mounting device; wherein the one or more gaskets are arranged between the laser base and the optical lens, and the thermal expansion coefficients of the laser base, the gaskets and the optical lens are sequentially decreased. One or more gaskets are arranged between the laser base and the optical lens, and the thermal expansion coefficient of each gasket is between the thermal expansion coefficient of the laser base and the thermal expansion coefficient of the optical lens, so that the gaskets can play a role in reducing thermal stress between the laser base and the optical lens, and the optical lens is effectively prevented from cracking; and the use reliability is improved. 本申请提供一种光学镜片的安装装置和激光器，安装装置包括激光器底座和一个或者多个垫片，安装装置上承载有光学镜片；其中，一个或者多个垫片设置于激光器底座和光学镜片之间，且激光器底座、垫片以及光学镜片的热膨胀系数依次递减。通过在激光器底座和光学镜片之间设置一个或者多个垫片，由于垫片的热膨胀系数介于激光器底座和光学镜片的热膨胀系
