A novel, to the best of our knowledge, approach is developed to realize a high-power compact efficient yellow-lime-green triple-color ${\rm Nd}:{{\rm YVO}_4}$ self-Raman laser. The 588 nm yellow laser, the 559 nm lime laser, and the 532 nm green laser are converted from the 1064 nm fundamental wave and the 1176 nm Stokes Raman field. The simultaneous three-color operation is accomplished with three stages to step-by-step generate the 588 nm, 559 nm, and 532 nm lasers by using three different lithium triborate (LBO) crystals. By tuning the temperature of each individual LBO crystal, the 588 nm, 559 nm, and 532 nm output powers can be nearly the same and concurrently up to 2.4 W at the incident pump power of 30 W, corresponding to a conversion efficiency of 24% for the total output power.

紧凑型高效大功率三色Nd：YVO ₄黄灰绿自拉曼激光器

据我们所知，开发了一种新颖的方法来实现高功率紧凑高效的黄石灰绿色三色$ {\ rm Nd}：{{\ rm YVO} _4} $自拉曼激光器。从1064 nm基波和1176 nm Stokes拉曼场转换了588 nm黄色激光，559 nm石灰激光和532 nm绿色激光。通过使用三个不同的三硼酸锂（LBO）晶体，分三步完成同时进行的三色操作，以逐步生成588 nm，559 nm和532 nm激光器。通过调节每个LBO晶体的温度，588 nm，559 nm和532 nm的输出功率可以几乎相同，并且在30 W的入射泵浦功率下最高可以同时达到2.4 W，相当于24％的转换效率用于总输出功率。
