利用非线性晶体 (BBO)的非共线匹配倍频效应 ,研制了实时测量高能量低重复频率超短激光脉冲宽度的单脉冲自相关仪 ,并对飞秒 (fs)参量放大器的输出脉冲宽度进行了测量 ,测得了 10 3fs的超短激光脉冲宽度。
A non-collinear matching frequency doubling effect of nonlinear crystal (BBO) was used to develop a single-pulse autocorrelator for real-time measurement of ultra-short laser pulse width with high energy and low repetition rate. The output pulse width of fs parametric amplifier The measurements were made and the ultrashort laser pulse width of 10 3fs was measured.
