Abstract

We demonstrate that Arbitrary-Detuning ASynchronous OPtical Sampling (AD-ASOPS) makes possible multiscale pump-probe spectroscopy with time delays spanning from picosecond to millisecond. The implementation on pre-existing femtosecond amplifiers seeded by independent free-running oscillators is shown to be straightforward. The accuracy of the method is determined by comparison with spectral interferometry, providing a distribution with a standard deviation ranging from 0.31 to 1.7 ps depending on experimental conditions and on the method used to compute the AD-ASOPS delays.

摘要

我们证明，任意失谐异步光学采样（AD - ASOPS）使跨越皮秒到毫秒时间延迟的多尺度泵浦 - 探测光谱学成为可能。在由独立自由运行振荡器注入种子的现有飞秒放大器上的实现被证明是直接的。该方法的准确性通过与光谱干涉测量法比较来确定，根据实验条件和用于计算AD - ASOPS延迟的方法，提供了一个标准偏差范围为0.31至1.7皮秒的分布。
