随着新型高效激光基质材料的不断出现以及激光二极管(LD)技术的不断提高,LD抽运的固体激光器已逐渐成为激光器发展的主流。目前固体激光器小型化的一个重要方向是微片激光器。微片激光器是一种具有固体微型腔结构的端面抽运激光器件,其典型结构是在激光介质的两个通光端面上分 With the continuous emergence of new and efficient laser matrix materials and the continuous improvement of laser diode (LD) technology, LD-pumped solid-state lasers have gradually become the mainstream of laser development. At present, one important direction of miniaturization of solid-state lasers is the use of a micro-chip laser. A microchip laser is an end-pumped laser device with a solid microcavity structure. The typical structure of the microchip laser is on the two light-transmitting end surfaces of the laser medium
