Electro-optic spectral shearing interferometry is implemented for the highly sensitive characterization of ultrashort pulses from a free-running source. A simple phase-locked-loop clock recovery circuit is used to extract the high-frequency microwave clock signal to drive the phase modulator for spectral shearing. We demonstrate accurate full temporal characterization of 200-fs pulses from an optical parametric oscillator at 5-pW average power.
电光光谱剪切干涉测量法用于对自由运行光源产生的超短脉冲进行高灵敏度表征。采用一个简单的锁相环时钟恢复电路来提取高频微波时钟信号,以驱动相位调制器进行光谱剪切。我们展示了对平均功率为5皮瓦的光学参量振荡器产生的200飞秒脉冲进行精确的全时域表征。
