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。
Reported a high efficiency Ti: Sapphire laser system consisting of a Littman cavity resonator and a single pass amplifier. When the pump laser (532um Nd: YAG) energy is 140mJ / pulse, the system outputs 22.5mJ / pulse at a single longitudinal mode near 800um. Conversion efficiency is 16%. The magnifying characteristics of Ti: Sapphire and the focus position of pump light of such systems are discussed.
