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.

该研究计划将集中在真空紫外线（VUV）中相干辐射源的演示，这是一个目前存在很少可调谐源的区域。基于被认为是有效能量存储介质的选定小分子的反斯托克斯拉曼散射，这些相干光源将利用过去几年通过激光光谱学获得的详细光谱信息。最初的实验将集中在XeF分子上，理论已经确定它是一个有希望的候选者。准分子的D - B跃迁的激光光谱将在超声速膨胀中进行，然后在更长的增益长度放电中进行振荡器实验。后续的研究将探索稀有气体和B柱二聚体作为150nm以下光谱区域可调谐激光器的潜在宿主。
