摘　　要：报道了一种可实时测量超短激光脉冲宽度及啁啾特性的干涉(8:1)自相关器.扫描频率为1～20Hz.测量误差小于3fs.主要用于自锁模Ti:Al_2O_3.Cr:LiSGAF等各种飞秒激光器光脉冲宽度的实时测量.Based on a commercially available audio speaker a real- time rapid scanning interferometric SHG autocorreiator that may monitor both the pulse-width and frequency sweep in ultrashort laser pulses is reported. The repetition rate of sweeping is 1-20 Hz, and the measurement error is below 3 fs. This apparatus can be used widely for monitoring and measuring interferometric autocorrelation traces of femtosecond pulses generated from self-mode-locked Ti : sapphire laser and those from any other kind of femtosecond pulse lasers.
