title: Generation of nanosecond infrared pulses tunable from 2.8 to 16 microm by efficient stimulated electronic Raman scattering.
abstract: A source of nanosecond IR pulses tunable from 2.8 to 16 microm (3500 to 630 cm(-1)) 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.
