Paper Abstract

Ultrafast time-dependent optical reflection and/or transmission spectroscopy can be used to measure time responses of materials and time arrivals between two unrelated ultrafast pulses. For example, a pump pulse, such as an x-ray pulse, excites a material, changing its refractive index. A spectrogram monitoring the change of intensity of a reflected or transmitted optical probe pulse can be used to indirectly monitor the refractive index change. Standard spectrogram deconvolution methods can be used to extract characteristics of both the material response and the probe pulse, but care must be taken to consider any experimental artifacts.
