Photodynamics of Condensed Phase Rare Gas Halides: Condensed Phase Exciplex Lasers

凝聚相激基复合体激光器最近被PI证明在固体和液体中都是如此。这些激光器具有吸引人的特性，如从真空紫外光到远红光的宽光谱覆盖范围，宽可调谐和前所未有的能量密度(展示了50千焦耳/升)。卤素掺杂稀有气体晶体、液体和高密度流体构成了研究反应性多体动力学最简单的模型系统。在这些体系中，光解离、扩散、复合和电荷转移动力学都是要严格审查的。实验研究的目的是获得与凝聚位相可调谐紫外光和真空紫外光激光器设计相关的基本光动力学参数，并对有希望的候选激光器的激光特性进行表征。这项工作将致力于(A)可能导致开发连续和可宽调谐的UV-VUV激光器的系统，以及(B)开发高温(直到室温)固态、超临界流体激光器。

Condensed phase exciplex lasers have recently been demonstrated by the PI in both solid and liquid phases. These lasers possess attractive properties such as wide spectral coverage from the vacuum ultraviolet to the far red, broad tunability and unprecedented energy densities (50 Kjoule/liter demonstrated). Halogen-doped rare gas crystals, liquids and high density fluids, constitute the simplest model systems for studies of reactive many-body dynamics. Photodissociation, diffusion, recombination and charge transfer dynamics are all amenable for rigorous scrutiny in these systems. The experimental studies are aimed at obtaining the fundamental photodynamical parameters pertinent to the design of condensed phase tunable UV and VUV lasers and the characterization of lasing properties on the promising candidates. The work will pursue (a) systems that may lead to the development of continuous and broadly tunable UV-VUV lasers, and (b) development of high temperature (up to room temperature) solid state, supercritical fluid lasers.
