Coherent Sources in the Vacuum Ultraviolet

该研究计划将重点展示真空紫外线（VUV）中的相干辐射源，该区域目前几乎不存在可调谐源。 基于已知为有效能量存储介质的选定小分子的反斯托克斯拉曼散射，这些相干源将利用过去几年通过激光光谱获得的详细光谱信息。 最初的实验将集中在 XeF 分子上，理论认为该分子是有希望的候选者。 准分子的 D B 跃迁的激光光谱将在超音速膨胀中进行，然后在较长增益长度放电中进行振荡器实验。 后续研究将探索稀有气体和 B 柱二聚体作为 150 nm 以下光谱区域可调谐激光器的潜在宿主。

This research program will focus on the demonstration of coherent sources of radiation in the Vacuum Ultraviolet (VUV), a region where few tunable sources presently exist. Based on anti-Stokes Raman scattering in selected small molecules that are known to be efficient energy storage media, these coherent sources would exploit the detailed spectroscopic information that has been obtained over the last few years by laser spectroscopy. Initial experiments will concentrate on the XeF molecule which theory has identified as a promising candidate. Laser spectroscopy of the D B transition of the excimer will be carried out in a supersonic expansion followed by oscillator experiments in longer gain length discharges. Subsequent studies will explore the rare gas and Column B dimers as potential hosts for tunable lasers in the spectral region below 150nm.
