Laser Spectroscopy of Stimulated Scattering in Collisionally Broadened Group IIA Metal Vapors.

摘要

This study is concerned with the development of efficient nonlinear materials which can generate 3-5 microns infrared (IR). Work involved the use of Ca and Sr metal vapors as electronic Raman scattering (SRS). This involved the development of narrow bandwidth pulse lasers, scattering cells, high speed IR detectors, and suitable experimental diagnostics to study the gain for SRS and its temporal development. It was found that SRS never generated, but instead, a variety of other nonlinear responses were readily induced, the most notable being superfluorescence (SF). Results of these studies of SF in the optically trapped principal resonance state of Ca(Sr) may be useful in the development or diagnostics of plasma based x-ray lasers.
