Atomic Sn, Sb, and Ge photodissociation lasers

Stimulated emission has been observed on the 380.1 nm line of atomic tin, the 326.7 nm line of atomic antimony, and the 326.9 nm line of atomic germanium following photodissociation of SnI2, SbI3, and GeI4 molecular vapors. A 193 nm ArF laser was used as the excitation source. Bond energies for the dissociation of monoiodides were estimated. Output energies of 200, 80, and 75 microjoules were obtained for 380.1, 326.7, and 326.9 nm transitions, respectively.
