瞬态吸收测量已成为皮秒光谱研究极快能级动力学的标准工具。在荧光样品中，受激荧光是一个竞争过程。在液体样品中，由于光的偏振，旋转扩散起作用。提出了一种重复皮秒光谱仪，由于其低功率，大大减少了受激荧光的发生，并且能够分离旋转扩散和水平动力学。
Transient absorption measurements have become a standard tool of picosecond spectroscopy in studying very fast level kinetics. In fluorescent samples stimulated fluorescence is a competing process. In liquid samples rotational diffusion is contributing due to the polarization of light. A repetitive picosecond spectrometer is presented that greatly reduces the occurrence of stimulated fluorescence due to its low power and is capable of separating rotational diffusion and level kinetics.
