查询词典 chemical fiber

The invention relates to a light pumping system for all-solid laser, particularly a light pumping system for disc type laser, comprising heat sink, laser crystal, optical fiber, plane reflector, a first concave reflector, a second concave reflector, and a third concave reflector, and adopting a structure that the plane reflector is between the optical fiber and the first concave reflector, to make the LD and laser cavity on the same side of the laser crystal, thus reducing the packaged size of the laser; the invention fixes the plane reflector on the heat sink to reduce the inclined incident angle of the pumped light beam, thus the pumped light can be fully absorbed, and the invention solves the problem of pumping efficiency and largely reduces the bulk of the laser, beneficial to the all curing of the product and ensuring the cooling requirement of the laser crystal.

本发明涉及全固体激光器的光泵浦系统，特别是一种盘式激光器的光泵浦系统。包括热沉1、激光晶体2、光纤3、平面反射镜4、第一凹面反射镜5、第二凹面反射镜6、第三凹面反射镜7，本发明采用平面反射镜位于光纤与第一凹面反射镜之间的结构，使LD和激光腔位于本发明激光晶体的同一侧，从而减小了激光器的封装尺寸；本发明将平面反射镜固定在热沉上，使泵浦光束斜入射角减小，泵浦光则能充分吸收，为此，本发明解决背景技术采用第一凹面反射镜使泵浦光束斜入射角过大引起的像散，泵浦光斑变形引起泵浦效率降低问题，使得本发明可选用大面积半导体制冷器，避免使用水冷，则激光器的体积大大减少，有利于产品的全固化，保证了激光晶体的散热要求。
