本文介绍了一种用波长为８０９ｎｍ的激光二极管（ＬＤ）端面泵浦厚度为１ｍｍ的微片ＮｄＹＶＯ４全固化固体激光器．器件结构上采用了一种独特的光学系统，该系统由分别用于ＬＤ激光束的耦合和聚焦的两部分组成．由ＮｄＹＶＯ４的一个平面与一个曲率半径为２１ｍｍ的球面镜组成半共焦腔，以获得高的转换效率．文中详细讨论了单横模运转时的泵浦光与激光腔模之间的匹配问题．当泵浦光功率为４００ｍＷ时，获得１５２ｍＷ的１０６４ｎｍ波长的ＴＥＭ００模激光输出．器件阈值功率为４８．３ｍＷ，总的光－光转换效率为３８％，斜效率为４３％．
In this paper, we introduce a microchip NdYVO4 solid-state solid-state laser with a thickness of 1mm by using a laser diode (LD) end facet with a wavelength of 809nm. The device is constructed using a unique optical system consisting of two parts for the coupling and focusing of the LD laser beam, respectively. A semi-confocal cavity consists of a flat surface of NdYVO4 and a spherical mirror with a radius of curvature of 21 mm for high conversion efficiency. In this paper, the matching between pump mode and laser cavity mode in single transverse mode operation is discussed in detail. At pump power of 400 mW, a TEMmode laser output of 152 mW at 1064 nm was obtained. The threshold power of the device is 48.3mW, the total light-to-light conversion efficiency is 38% and the ramp efficiency is 43%.
