研制了一种采用冷却Yb：YLF晶体的二极管泵浦啁啾脉冲再生放大器。在20-Hz重复频率下，输出脉冲能量为30 mJ。获得了68%的高有效提取效率，这归因于在低温下降低饱和注量和在再生放大期间的高有效脉冲能量注量。利用平行光栅对进行脉冲压缩后，获得了18 mJ的脉冲能量和795 fs的脉冲宽度。
A diode-pumped chirped-pulse regenerative amplifier with a cooled Yb:YLF crystal has been developed. The output pulse energy is 30 mJ at 20-Hz repetition rate. A high effective extraction efficiency of 68% is obtained, which is attributed to reduced saturation fluence at low temperature and to a high effective pulse energy fluence during regenerative amplification. After pulse compression by use of a parallel grating pair, 18-mJ pulse energy and 795-fs pulse duration are obtained.
