Abstract

We present an ultraviolet (UV) - extreme-ultraviolet (XUV) pump-probe beamline with applications in ultrafast time-resolved photoelectron spectroscopy. The UV pump pulses, tuneable between 255 and 285 nm and with µJ-level energy, are generated by frequency up-conversion between ultrashort visible/infrared pulses and visible narrow-band pulses. Few-femtosecond XUV probe pulses are produced by a high-order harmonic generation source equipped with a state-of-the-art time-delay compensated monochromator. Two-colour UV-XUV sidebands are used for a complete in situ temporal characterization of the pulses, demonstrating a temporal resolution of better than 20 fs. We validate the performances of the beamline through a UV-XUV pump-probe measurement on 1,3-cyclohexadiene, resolving the ultrashort dynamics of the first conical intersection. This instrument opens exciting possibilities for investigating ultrafast UV-induced dynamics of organic molecules in ultrashort time scales.

摘要

我们展示了一种用于超快时间分辨光电子能谱的紫外（UV）-极紫外（XUV）泵浦-探测光束线。紫外泵浦脉冲的波长在255至285纳米之间可调，能量为微焦级，由超短可见/红外脉冲与可见窄带脉冲之间的频率上转换产生。少飞秒XUV探测脉冲由配备了最先进的时间延迟补偿单色仪的高次谐波产生源产生。双色UV-XUV边带用于对脉冲进行完整的原位时间表征，展示了优于20飞秒的时间分辨率。我们通过对1,3-环己二烯进行UV-XUV泵浦-探测测量来验证光束线的性能，解析了第一个锥形交叉点的超快动力学。该仪器为在超短时间尺度上研究超快紫外诱导的有机分子动力学开辟了令人兴奋的可能性。
