We demonstrate a novel time domain timing jitter characterization method for ultra-low noise mode-locked lasers. An asynchronous optical sampling (ASOPS) technique is employed, allowing timing jitter statistics on a magnified timescale. As a result, sub femtosecond period jitter of an optical pulse train can be readily accessible to slow detectors and electronics (~100 MHz). The concept is applied to determine the quantum-limited timing jitter for a passively mode-locked Er-fiber laser. Period jitter histogram is acquired following an eye diagram analysis routinely used in electronics. The identified diffusion constant for pulse timing agrees well with analytical solution of perturbed master equation.
我们展示了一种用于超低噪声锁模激光器的新型时域定时抖动表征方法。采用了异步光学采样（ASOPS）技术，可在放大的时间尺度上进行定时抖动统计。因此，慢探测器和电子设备（~100 MHz）能够轻松获取光脉冲序列的亚飞秒周期抖动。该概念被应用于确定被动锁模铒光纤激光器的量子极限定时抖动。通过电子学中常用的眼图分析获取周期抖动直方图。所确定的脉冲定时扩散常数与受扰主方程的解析解吻合良好。
