Abstract
The effect of concentration on laser threshold is examined theoretically and experimentally for Rhodamin B and Rhodamin 6G. Laser action is obtained in the region from 1 · 10−6 mol to 2.5 · 10−1 mol.
Lasing in organic dye solutions which are excited by a pulslaser is possible in a broad concentration range. For high concentrations laser action is limited by fluorescence quenching and increasing losses (diffraction, thermal effects, and bleaching). For low concentrations the limit is given by the losses of the used experimental set-up. In the present work the influence of the concentration on the exciting intensity at laserthreshold is examined for Rhodamin B and Rhodamin 6G solutions.
