A diode-pumped, cryogenic-cooled Yb:YAG regenerative amplifier utilizing gain-narrowing has been developed. A 1.2-ns chirped-seed pulse was simultaneously amplified and compressed in the regenerative amplifier, which generated a 35-ps pulse with ~8-mJ of energy without a pulse compressor. Second-harmonics of the amplified pulse was used to pump picosecond two-color optical parametric amplification.
已研制出一种利用增益窄化的二极管泵浦、低温冷却的Yb:YAG再生放大器。一个1.2纳秒的啁啾种子脉冲在再生放大器中同时被放大和压缩，在没有脉冲压缩器的情况下产生了一个能量约为8毫焦的35皮秒脉冲。放大脉冲的二次谐波被用于泵浦皮秒双色光参量放大。
