In the landscape of ultrafast spectroscopic tools, the deep- and near-ultraviolet ranges (200-400 nm) have lagged behind due to the lack of tunability of both the pump and the probe pulses in this range. With the advent of novel nonlinear optical methods, this has now become possible. In this perspective, I will review some of the recent studies in the 250-400 nm range on (bio)chemical systems in order to stress the capabilities of ultrafast deep-UV spectroscopy to unravel new phenomena. This will serve as a basis to dwell on the promise and the new directions not only for molecular systems but also materials in solid or nanostructured form.
在超快光谱学工具的领域中，深紫外和近紫外范围（200-400nm）由于该范围内的泵浦和探测脉冲的可调谐性不足而落后。随着新型非线性光学方法的出现，现在已经成为可能。在这个视角中，我将回顾一些在 250-400nm 范围内关于（生物）化学系统的最新研究，以强调超快深紫外光谱学揭示新现象的能力。这将作为一个基础，不仅探讨分子系统，还探讨固体或纳米结构形式的材料的前景和新方向。
