摘要
描述了利用双光路自参考技术测量红外飞秒脉冲载波包络相移的方法,并通过建立的红外飞秒脉冲载波包络相移测量装置,实验测量了自主搭建的可调谐光学参量放大系统输出的红外飞秒激光脉冲的载波包络相移.对于1.6μm的激光脉冲,测量得到在100s内其相位抖动为115mrad(rms).实验结果表明双光路法具有易于调节、测量方便、应用性强等优点.
We describe a self-referencing two-path interferometer designed to measure the carrier-envelope phase stability. In experiment, we measure the carrier-envelope phase (CEP) stability of a home-made infrared tunable OPA laser pulses with the self-referencing two-path interferometer. When the wavelength of the incident pulses is 1.6 um, the CEP fluctuation is 115 mrad (rms) in 100 seconds. The interferometer can provide an accurate and quick measurement of the pulse CEP.
