【摘要】 采用坩埚下降法生长了Ｃｒ３＋∶ＬｉＳｒＡｌＦ６（Ｃｒ∶ＬｉＳＡＦ）晶体。以功率为９００ｍＷ，波长为４８８ｎｍ的单线氩离子激光泵浦６ｍｏｌ％的Ｃｒ∶ＬｉＳＡＦ晶体，实现了Ｃｒ∶ＬｉＳＡＦ激光器的飞秒级自锁模运转，得到了脉冲宽度为４０ｆｓ，重复频率为１００ＭＨｚ，平均输出功率为４５ｍＷ的稳定的锁模脉冲序列。用闪光灯泵浦１ｍｏｌ％的Ｃｒ∶ＬｉＳＡＦ激光棒，在输入能量为１２０Ｊ时，得到了１２７０ｍＪ的激光输出，斜效率达２．２７％。更多还原

【Abstract】 Cr 3+ ∶LiSrAlF 6(Cr∶LiSAF)crystals are grown by Bridgman method. Self mode locked operation is achieved in the femtosecond range by using 6mol% Cr∶LiSAF crystals.With 900mW pump power from an argon ion laser of 488nm line,pulses as short as 40fs are obtained at the repetition rate of 100MHz and with an average output power of 45mW.An output of 1270mJ,slope efficiencies of 2.27% are obtained at the input power of 120J when an 1 mol% the Cr∶LiSAF crystal is pumped with flashlamp.更多还原
