高平均功率皮秒Yb:YAG薄盘激光器正在Hilase开发。紧凑的1 mJ/100 kHz和4 mJ/100 kHz零声子线泵送再生放大器PERLA C与CVBG压缩机提供<2 ps长脉冲在几乎衍射限制的光束。输出成功地转换为2次和4次谐波频率，转换效率高。高能、qcw泵浦光束线PERLA B在基本空间模式下工作在45mJ/1kHz，脉冲长度< 2ps。其二级放大器正在组装中，提取了1.8 J。报道了Hilase中心所有薄盘光束线的最新发展状况。
High average power picosecond Yb:YAG thin-disk lasers are being developed at Hilase. A compact 1 mJ/100 kHz and 4 mJ/100 kHz zero-phonon-line-pumped regenerative amplifiers PERLA C with a CVBG compressor provide <2 ps long pulses in a nearly diffraction-limited beam. The output was successfully converted to 2nd and 4th harmonic frequency with high conversion efficiency. High energy, QCW-pumped beamline PERLA B is operated at 45mJ/1kHz in fundamental spatial mode and pulse length < 2ps. Its second stage amplifier is being assembled and 1.8 J was extracted. The latest development status of all thin-disk beamlines at the Hilase center is reported.
