Frequency up-conversion by the anti-Stokes Raman laser process offers interesting perspectives for the generation of tunable uv-laser radiation. Systematic studies of the atomic Tl-system have led to small signal energy conversion efficiencies of more than 70 % and maximum output energies in the saturated regime of up to 5 mJ for the conversion of 535 nm into 377 nm radiation. In case of Tl the energy shift is about 7800 cm-1. Considerable larger energy shifts are possible with realized novel anti-Stokes lasers using atomic Sn and Pb. Further aspects and possibilities of this conversion technique will be discussed.
