本文报道了一台利用1.064 μ mNd：YAG激光器的二阶斯托克斯频移工作的1.485 μm外腔金刚石拉曼激光器。1.63产生了5kHz的W脉冲，量子转换效率为71%，光束质量优良。数值模拟证实，最佳操作实现低输出耦合反射率。
We report an efficient 1.485 μm external cavity diamond Raman laser operating on the 2nd Stokes shift of a 1.064 μm Nd:YAG pump laser. 1.63 W pulsed at 5 kHz is produced with a quantum conversion efficiency of 71% and excellent beam quality. Numerical modelling confirms that optimal operation is achieved with low output coupling reflectivity.
