We report a pulsed Raman laser at 1193 nm based on synthetic diamond crystals with a record output power of 24.5 W and a slope efficiency of 57%. We compared the performance of an anti-reflection coated crystal at normal incidence with a Brewster cut sample. Raman oscillation was achieved at both room temperature and under cryogenic operation at 77 K. Modeling of these experiments allowed us to confirm the value of Raman gain coefficient of diamond, which was found to be 13.5 ± 2.0 cm/GW for a pump wavelength of 1030 nm.
我们报道了一种基于人造金刚石晶体的1193纳米脉冲拉曼激光器，其输出功率达到24.5瓦，斜率效率为57%，创下了纪录。我们将正常入射时的增透膜晶体与布儒斯特切割样品的性能进行了比较。在室温以及77K的低温操作条件下均实现了拉曼振荡。对这些实验进行建模使我们能够确定金刚石的拉曼增益系数值，对于1030纳米的泵浦波长，该值为13.5±2.0厘米/吉瓦。
