【摘要】 报道了采用三镜腔结构的Ｃｒ∶ＬｉＳＡＦ激光器在低功率的氩离子单谱线激光泵浦下，连续光、自调Ｑ、自锁模和自调Ｑ－自锁模的运转特性。当泵浦功率为８６０ｍＷ时，在腔内不加任何调制器和可饱和吸收体，可实现自锁模运转，得到重复频率为１５０ＭＨｚ，脉冲宽度为５１ｆｓ，输出功率为４８ｍＷ的脉冲序列更多还原

【Abstract】 The investigation on the continuous wave, self Q switched, self mode locked, and self Q switched self mode locked operations of a Cr∶LiSAF laser with a three mirror cavity and with low pump power from an argon ion laser at the 488 nm line are reported. Without any active modulator or saturable absorber in the cavity, 51 fs pulses at a repetition of 150 MHz and with an average output power of 48 mW for 860 mW pump power are obtained.更多还原
