摘要
报道了由Ｌｉｔｔｍａｎ式腔结构振荡器和一级单通放大器组成的高效率Ｔｉ：Ｓａｐｐｈｉｒｅ激光系统。泵浦激光（５３２ｕｍＮｄ：ＹＡＧ）能量为１４０ｍＪ／ｐｕｌｓｅ时，该系统在８００ｕｍ附近单纵模输出为２２．５ｍＪ／ｐｕｌｓｅ。转换效率为１６％。讨论了Ｔｉ：Ｓａｐｐｈｉｒｅ的放大特性及此类系统的泵浦光聚焦位置等问题。
A high efficiency Ti:Sapphire laser system consisted of a Littman configurationoscillator and one stage single pass amplifier is presented. While the pumping source (532urn Nd:YAG)energy is 140 mJ/pulse, the SLM(single longitudinal mode)output of thesystem reaches 22.5 mJ in the vicinity of 800 nm. The conversion efficiency is about16%.In addition,the amplification characteristics of the Ti:Sapphire and the focusingpositions of the pump laser are discussed.
