摘　　要：报道了一台激光二极管(LD)双端面抽运Nd:YLF和Nd:YAG双晶体串接多波长输出脉冲激光器。在抽运能量40.5mJ,电光调Q重复频率500Hz的工作条件下,获得单脉冲能量约为6mJ的1064nm/1053nm双波长激光脉冲输出,光-光转换效率约为14.8%。相同抽运条件下在腔内插入I类相位匹配LBO晶体作为非线性频率转换器,获得了脉冲总能量为3.6mJ的526.5、529.0、532.0nm三波长同时输出,由抽运光到输出绿光脉冲的转换效率约为8.9%,测得光束质量因子分别为M2x=1.61,My2=1.25。Simultaneous multi-wavelength pulsed laser is achieved in dual-end-pumped composite laser slab composed of Nd：YLF and Nd：YAG crystals.As much as 6 mJ of laser output at 1064 nm and 1053 nm wavelengths is obtained with an incident pump pulse energy of 40.5 mJ at 500 Hz repetition rate,corresponding to an optical-optical conversion efficiency of 14.8%.By inserting a LBO crystal in the cavity,three green wavelengths of 526.5,529.0 and 532.0 nm lasing is detected simultaneously.The total pulse energy is about 3.6 mJ under 40.5 mJ of incident pump pulse energy at 500 Hz repetition rate.The optical-optical conversion efficiency is 8.9%.The beam quality factors are M2x=1.61,M2y=1.25.
