Abstract
We have observed stimulated emission on the transitions near 518 nm following pulsed laser excitation of Mg vapor near the resonance at 285 nm. The emission has a divergence similar to the pump laser and closely follows the incident laser in time. The mechanism apparently involves pumping an accidental coincidence and , permitting depletion of the lower level of the triplet transition. Photoionization of the Mg vapor creates a large electron density (≲1013 cm−3); electron-impact collisions are presumed to mediate the process, transferring population from the laser-pumped level to the triplet manifold.
