Abstract

A source of nanosecond IR pulses tunable from 2.8 to 16 um (3500 to 630 cm-') is obtained by stimulated electronic Raman scattering (SERS) on the cesium 6s-5d transition. Reliable rhodamine and DCM dye-laser pulses are frequency shifted with up to 10% quantum conversion efficiency to obtain up to 2 mJ of IR pulse energy, a 5-25X improvement in energy over previous SERS infrared generation. The tuning curve structure and unwanted amplified spontaneous emission lines are also substantially reduced.
