Abstract

We describe an efficient Er:YAG laser that is resonantly pumped using continuous-wave (CW) laser diodes at 1470 nm. For CW lasing, it emits 6.1 W at 1645 nm with a slope efficiency of 36%, the highest efficiency reported for an Er:YAG laser that is pumped in this manner. In Q-switched operation, the laser produces diffraction-limited pulses with an average power of 2.5 W at 2 kHz PRF. To our knowledge this is the first Q-switched Er:YAG laser resonantly pumped by CW laser diodes.

摘要

我们描述了一种高效的铒钇铝石榴石（Er:YAG）激光器，它由1470纳米的连续波（CW）激光二极管进行共振泵浦。对于连续波激光，它在1645纳米处发射6.1瓦的功率，斜率效率为36%，这是采用这种方式泵浦的Er:YAG激光器所报道的最高效率。在调Q操作中，该激光器产生衍射极限脉冲，在2千赫兹的脉冲重复频率（PRF）下平均功率为2.5瓦。据我们所知，这是第一台由连续波激光二极管共振泵浦的调Q Er:YAG激光器。
