二极管抽运百瓦级红光固体激光器

Hector-Watt-Level Diode Pumped Solid-State Red Laser

采用大功率二极管侧面抽运Nd:YAG晶体,在含望远系统的双棒串接四镜折叠腔结构下,利用双声光开关调Q及三硼酸锂(LBO)晶体内腔倍频的方式,通过谐振腔和倍频晶体参数优化设计,获得了重复频率为10 kHz,波长为659.5 nm,平均功率大于105 W的高功率红光激光输出,光-光转换效率达6.6%。

A multiple diode-arrays side-pumped two-rod series connection four-mirror resonator in which has a telescope system has been demonstrated.Using two acousto-optic Q-switches and the intra-cavity frequency doubling of LBO crystal,up to 105 W output at 695.5 nm with the repetition rate of 10 kHz is obtained by resonant cavity and frequency doubling systal parameters optimal design;the optical-to-optical conversion is up to 6.6%.
