LD-pumped eye-safe Nd:YAG laser at 1.44μm

利用808 nm LD作泵浦源,通过合理的谐振腔镜膜层设计,实现了Nd:YAG的4Fa/2→4I13/2能级跃迁,获得了1.44 μm人眼安全波段激光的连续和脉冲运转.在泵浦功率为1.5 W的条件下,激光器连续运转时,腔内放入布氏片,获得268 mW的稳定TEM00模线偏振激光输出,激光阈值380 mW,斜效率达23.9%,M2因子小于1.3.用新型饱和吸收体V:YAG代替布氏片垂直于光路放置,获得了平均输出功率36 mW,脉冲宽度106 ns,脉冲重复频率52 kHz仍然是线偏振的激光输出,相应脉冲峰值功率和单脉冲能量分别为6.5 W和0.69μJ.
