摘　　要：设计了一种高功率的固体皮秒脉冲激光放大器。采用增益介质为Nd∶YAG材料的传导冷却端面泵浦板条放大器结构设计,通过板条结构多角度放大,实现对皮秒脉冲激光的四程放大。分析板条端面切角与激光入射角度的选取对填充因子以及激光功率放大的影响。最终实现了在种子光重复频率为100 kHz、激光脉冲宽度为9.6 ps的工作条件下,系统输出激光功率为103 W,单脉冲能量为1.03 mJ。In this study,we design a high-power compact solid-state picosecond pulse laser amplifier.We design a conducting-cooled end-pumped slab laser amplifier for which the gain medium is Nd∶YAG.We achieve the four-pass amplification of the picosecond pulsed laser through the slab multi-angle magnification technology.The influences of the selection of cutting angles of slat end face and laser incident angles on the filling factor and laser power amplification are analyzed.The output power of a mode-locked laser with 9.6-ps pulse duration and 100-kHz repetition rate respectively,is amplified up to 103 W;the single-pulse energy is 1.03 mJ.
