We demonstrate the generation of 1.1 J pulses of picosecond duration at 1 kHz repetition rate (1.1 kW average power) from a diode-pumped chirped pulse amplification Yb:YAG laser. The laser employs cryogenically cooled amplifiers to generate =1030 pulses with average power of up to 1.26 kW prior to compression with excellent beam quality. Pulses are compressed to 4.5 ps duration with 90% efficiency. This compact picosecond laser will enable a variety of applications that require high energy ultrashort pulses at kilohertz repetition rates.
我们展示了从二极管泵浦啁啾脉冲放大Yb:YAG激光器以1 kHz重复频率（平均功率1.1 kW）产生持续时间为皮秒级的1.1 J脉冲。该激光器采用低温冷却放大器，在压缩之前产生平均功率高达1.26 kW、脉宽为1030 ps且光束质量优异的脉冲。脉冲被压缩至4.5 ps的持续时间，效率为90%。这种紧凑型皮秒激光器将能够实现各种需要千赫兹重复频率的高能量超短脉冲的应用。
