We present what is, to the best of our knowledge, the first diode-pumped Nd:YAG laser emitting at 899 nm and below, based on the (4)F(3/2) - (4)I(9/2) transition, generally used for a 946 nm emission. A power of 630 mW at 899 nm has been achieved in cw operation and 16 mW at 884 nm with a fiber-coupled laser diode emitting 9 W at 808 nm. Intracavity second-harmonic generation in cw mode has also been demonstrated with a power of 100 mW at 450 nm by using a LiB(3)O(5) nonlinear crystal.
据我们所知，我们展示了首个基于通常用于946nm发射的（4）F（3/2） - （4）I（9/2）跃迁、在899nm及以下波长发射的二极管泵浦Nd:YAG激光器。连续波运行时，在899nm处实现了630mW的功率，使用在808nm处发射9W的光纤耦合激光二极管，在884nm处实现了16mW的功率。通过使用LiB（3）O（5）非线性晶体，还展示了连续波模式下的腔内二次谐波产生，在450nm处功率为100mW。
