论文摘要
深层紫外线是介电的带隙区域，对于已建立的超快光谱法而言，不容易访问。在这里，引入了瞬态吸收和分散光谱，在非连续性生成没有随后的光学元件的情况下，在非连续性生成后立即使用量身定制的深紫外线。探索了延迟的动态弗朗兹 - 卡尔德斯效应和几乎瞬时的光学kerr效应共存的延迟动力学效果，探索了钻石的近袋中钻石区域。
The deep ultraviolet, the bandgap region of dielectrics, is not readily accessible for established methods of ultrafast spectroscopy. Here, a miniature beamline, where a tailored deep ultraviolet field is used immediately after the noncollinear generation without subsequent optical elements, is introduced for transient absorption and dispersion spectroscopy. The near-bandgap region of diamond in the presence of a few-femtosecond pump pulse is explored where the delayed dynamical Franz-Keldysh effect and the almost instantaneous optical Kerr effect coexist.
