Vacuum-ultraviolet anti-Stokes Raman laser with atomic selenium.
The achievement of anti-Stokes Raman-laser oscillation in atomic Se at 158.7 and 167.5 nm using pump-laser radiation at 199.5 and 254.8 nm is reported. The necessary population inversion between the (1)S(0) and lower (1)D(2) or (3)P states is achieved by photodissociation of COSe molecules with ArF-laser radiation. Low-threshold pump energies of 0.5 and 20 microJ, respectively, indicate the possibility of generating high-power tunable VUV radiation.
