Resonantly Enhanced, Nonlinear Generation of Tunable, Coherent, Vacuum Ultraviolet (VUV) Light in Atomic Vapors.

摘要

The emphasis of this paper is on physical factors determining the relative VUV output in the various tuning ranges. Before actually discussing VUV generation, however, a multiphoton ionization experiment is described that graphically illustrates the importance of two-photon resonance in nonlinear phenomena in gases and also serves to acquaint the reader with the arrangement of energy levels in Sr, the atomic vapor on which most of our VUV studies have been concentrated.
