介绍了一种紧凑、可靠、高功率、高对比度的非共线光参量啁啾脉冲放大系统。利用宽带钛宝石振荡器和基于光栅基的展宽和压缩，在重复率为10 Hz时，第一类β-BBO光学参量啁啾脉冲放大器的啁啾脉冲从0.1nJ放大到122mJ，总增益大于10(9)。放大后脉冲压缩到19-fS，峰值功率为3.2TW，平均功率为0.62W，预脉冲对比度在皮秒时间尺度上小于10(-8)。
We describe a compact, reliable, high-power, and high-contrast noncollinear optical parametric chirped-pulse amplifier system. With a broadband Ti:sapphire oscillator and grating-based stretching and compression, the chirped pulses are amplified from 0.1 nJ to 122 mJ in type I beta-barium borate optical parametric chirped-pulse amplifiers with a total gain of over 10(9) at 10 Hz repetition rate. Pulse compression down to 19-fs duration achieved after amplification indicates a peak power of 3.2 TW at an average power of 0.62 W. The prepulse contrast is measured to be less than 10(-8) on picosecond time scales.
