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.

固体和液体相中的PI最近证明了冷凝相激光激光。 这些激光器具有吸引人的特性，例如从真空紫外线到远红色，宽阔的可调性和前所未有的能量密度（50 kjoule/liter证明）的宽光谱覆盖率。 卤素掺杂的稀有气体晶体，液体和高密度流体构成了最简单的模型系统，用于研究反应性多体动力学。 在这些系统中，光电解离，扩散，重组和电荷转移动力学都可以进行严格的审查。 实验研究旨在获得与凝聚相可调紫外线和VUV激光器的设计有关的基本光动力学参数，以及在有希望的候选者上的激光特性的表征。 这项工作将追求（a）可能导致连续且宽阔的UV-VUV激光器的发展，以及（b）高温（升至室温）固态，超临界流体激光器的发展。
