Abstract
Lasers based upon stimulated anti-Stokes Raman scattering have recently been demonstrated,1,2 and such anti-Stokes Raman lasers (ASRL) show great potential as efficient upconverters for many currently available laser sources. In this paper, recent advances in characterizing and creating new ASRL devices are summarized. The tuning, output power, and saturation behavior of the ASRL are studied in the UV using a Raman medium of inverted metastable thallium atoms. The possibility of upconverting various excimer lasers via anti-Stokes scattering is described, and experimental results for a 20-kW/pulse 149-nm bromine ASRL are given. Finally the possibility of a widely tunable, chemically excited, VUV anti-Stokes laser is discussed; and initial spectroscopic studies aimed at a 135-170-nm CO Raman laser are presented.
