摘要
报道了利用简化的频率分辨光学开关法快速测量飞秒激光脉冲,并形成反馈,控制液晶空间光调制器,补偿非线性光纤飞秒激光放大器输出脉冲的啁啾,获得了脉冲宽度74fs的变换极限脉冲。
A close-loop chirp compensation system which consists of a simplified frequency-resolved optical gating(FROG) device and liquid crystal spatial light modulator(LC-SLM) is demonstrated.Femtosecond laser pusles are measured by using simplified frequency-resolved optical grating.The phase feedback signals derived from the simplified FROG control the LC-SLM to compensate the chirp of pulses.As a result,74-fs transform-limited pulses are obtained from nonlinear fiber femtosecond laser amplifier.
