High Efficiency SLM Littman Configuration Ti:Sapphire Laser System
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(532 nm Nd:YAG)能量为140 mJ/pulse时,该系统在800 nm附近单纵模输出为22.5 mJ/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。
Abstract
A high efficiency Ti:Sapphire laser system consisted of a Littman configuration oscillator and one stage single pass amplifier is presented. While the pumping source (532 nm Nd:YAG) energy is 140 mJ/pulse, the SLM (single longitudinal mode) output of the system reaches 22.5 mJ in the vicinity of 800 nm. The conversion efficiency is about 16%. In addition, the amplification characteristics of the Ti:Sapphire and the focusing positions of the pump laser are discussed.
