Time-resolved optical spectroscopy represents an effective non-invasive approach to investigate the interplay of different degrees of freedom, which plays a key role in the development of novel functional materials. Here, we present magneto-acoustic data on Ni thin films on SiO as obtained by a versatile pump-probe setup that combines transient grating spectroscopy with time-resolved magnetic polarimetry. The possibility to easily switch from a pulsed to continuous wave probe allows probing of acoustic and magnetization dynamics on a broad time scale, in both transmission and reflection geometry.
时间分辨光谱学是一种有效的非侵入性方法，用于研究不同自由度之间的相互作用，这在新型功能材料的开发中起着关键作用。在此，我们展示了通过一种多功能泵浦-探测装置获得的SiO上Ni薄膜的磁声数据，该装置将瞬态光栅光谱学与时间分辨磁极化测量相结合。能够轻松地从脉冲探测切换到连续波探测，这使得在透射和反射几何结构中，能够在很宽的时间尺度上探测声学和磁化动力学。
