摘要
报道了５００ｍＷ激光二极管端面泵浦Ｃｒ∶ＬｉＳＡＦ激光器连续运转的实验研究结果．特别是在分析了泵浦光与腔模的耦合情况后，提出了一套与泵浦源相适应的准直聚焦系统，提高了耦合效率．实验对两种不同掺杂浓度和不同形状的Ｃｒ∶ＬｉＳＡＦ晶体进行了研究，在８５０ｎｍ的中心波长处获得最大输出功率分别为２０ｍＷ和１３ｍＷ，斜效率分别为１０．３％和７．８％。
High efficiency collimating and focusing system for the LD end pumped the Cr∶
LiSAF laser is analyzed and reported in this paper.The pump source is 500mW laser diode,and
two kind of Cr∶LiSAF crystals with different Cr concentration and shape are performed.It is
obtained the CW operation with this pump system at the wavelength of 850nm.The maximum
output power is 20mW and 13mW,the slop efficiency is 10 3% and 7 8% respectively.
