We report the demonstration of a diode-pumped chirped pulse amplification Yb:YAG laser that produces λ=1.03 μm pulses of up to 1.5 J energy compressible to sub-5 ps duration at a repetition rate of 500 Hz (750 W average power). Amplification to high energy takes place in cryogenically cooled Yb:YAG active mirrors designed for kilowatt average power laser operation. This compact laser system will enable new advances in high-average-power ultrashort-pulse lasers and high-repetition-rate tabletop soft x-ray lasers. As a first application, the laser was used to pump a 400 Hz λ=18.9 nm laser.
我们报道了一种二极管泵浦啁啾脉冲放大Yb:YAG激光器的演示，该激光器产生波长λ = 1.03μm、能量高达1.5J的脉冲，在500Hz的重复频率下（平均功率750W）可压缩至亚5ps的持续时间。高能量放大在为千瓦平均功率激光运行设计的低温冷却Yb:YAG有源镜中进行。这种紧凑的激光系统将推动高平均功率超短脉冲激光器和高重复频率桌面软X射线激光器取得新进展。作为首个应用，该激光器被用于泵浦一台400Hz、λ = 18.9nm的激光器。
