我们演示了被动调Q的2%掺杂的Er：YAG激光器操作在人眼安全的区域与次5纳秒脉冲宽度使用Cr ~（2+）：ZnSe作为可饱和吸收体。描述了在突发模式下操作的杆几何形状和连续操作的微板几何形状。微板几何形状产生6 nsec被动Q开关脉冲，具有超过1.5瓦的输出功率和多千赫脉冲重复率。激光器是用1534 nm光纤激光器谐振泵浦的。
We demonstrate passively Q switched 2% doped Er:YAG laser operation in the eyesafe region with sub 5 nsec pulse widths using Cr2+:ZnSe as a saturable absorber. A rod geometry operating in the burst mode and a micro slab geometry operating continuously are described. The micro slab geometry generates 6nsec passively Q switched pulses with over 1.5 Watt of output power and with multi kilohertz pulse repetition rates. The lasers are resonantly pumped with a 1534nm fiber laser.
