Abstract

This paper reports what we believe to be the first observations of stimulated, anti-Stokes Raman laser emission. A metastable Tl^*(6p ²p^o_3/2) population inversion was created by selective photodissociation of TlCl, and Raman scattering using 532 nm and 355 nm pump lasers resulted in stimulated emission at 376 nm and 278 nm, respectively. Likewise, inverted I^*(5p^{5 2}P^o_1/2) atoms have been used as a Raman medium; and with a 206 nm pumping source, we have generated tunable VUV radiation at 178 nm.
