氢分子中的受激反斯托克斯拉曼散射允许产生连续可调谐的窄带辐射，其带宽可达真空紫外（VUV）窗口材料的透射极限。同时照射UV泵浦辐射（在本申请中，波长λ = 372 nm的染料激光器辐射）和波长对应于第一斯托克斯分量的辐射允许在远VUV中效率显著增加近2个数量级。在未聚焦的泵浦辐射通过在VUV拉曼单元之前的高压拉曼单元期间，以简单的方式产生附加的斯托克斯辐射。
Stimulated anti-Stokes Raman scattering in molecular hydrogen allows for the generation of continuously tunable narrow-bandwidth radiation down to the transmission limit of vacuum ultraviolet (VUV) window materials. Simultaneous irradiation of UV-pump radiation (in this application, dye laser radiation of wavelength lambda = 372 nm) and of radiation whose wavelength corresponds to the first Stokes component allows a considerable increase in efficiency-by nearly 2 orders of magnitude in the far VUV. The additional Stokes radiation is generated in a simple manner during the passage of the unfocused pump radiation through a high-pressure Raman cell that precedes the VUV Raman cell.
