| Abstract: | Coherent infrared radiation tunable between 1.6 and 3.2 μm was generated with a pulsed dye laser by 6s−5d 5/2 stimulated electronic Raman scattering in caesium vapour. We describe a technique using thermal dissociation to reduce the density of caesium dimers in a heat-pipe oven, which produced a factor of 7 reduction in Raman threshold. The threshold displayed a marked dependence on pump bandwidth. |
