Stimulated electronic Raman scatterng from the 6s ²S _1/2 to the 5d ²D_5/2 state of cesium

Abstract

The Raman transition 6s 2S1/2-5d 2D 5/2 in atomic cesium was stimulated to emit at 2.38 μ by light at 532 nm from a frequency-doubled Nd: YAG laser. With 2 mJ energy in a 10-ns single-mode pulse of green light, a quantum efficiency of 7% for conversion to the infrared light was measured. No tunable infrared stimulated Raman emission could be generated with as much as 7 mJ energy from a multimode dye laser tuned around 601 nm.
