Abstract

For atomic species of molybdenum extracted by pulsed laser deposition and isolated in Ar matrix at 11 K the photoluminescence spectra in the range from 360 nm to 620 nm are recorded under excitation of the z⁷P absorption triplet by the 355 nm laser pulses. Emission lines at 496.7, 548.1 and 602.0 nm are assigned to atomic transitions from Mo b⁵D, a⁵P and a⁵G to the ground a⁷S state and the slightly red shifted peaks at 501.6, 550.3 and 603.9 nm are ascribed to atoms at different matrix sites due to preparation. Values of the stimulated emission cross section and of the optical gain coefficient obtained from experiment for the Mo/Ar solid lie in the range of (1 divided by 25)X 10^-20 cm² and up to 0.29 cm^-1, respectively and are comparable with those of other three- level laser systems.
