Experiments on optically pumped three-level dimer lasers

Abstract

Stable unidirectional ring laser oscillation of optically pumped dimer molecules is reported. In the case of Na2, single-frequency output powers up to 200 mW tunable over a range of 4 GHz were obtained. By means of oscillator amplifier systems the forward-backward amplification profiles and the level splitting due to the dynamic Stark effect were measured.
