The influence of additions with electron-donor and electron-acceptor properties on the lasing properties and photostability of active aqueous micellar solutions of certain rhodamines during their excitation by flash lamps has been studied. A stabilizing influence of ascorbic acid on the lasing parameters of rhodamine solutions under different spectral conditions of excitation has been observed. It was found that in the presence of added substances with electron-acceptor properties (m-dinitrobenzene, cyclooctatetraene) a marked decrease of reversible stimulated absorption in the solution is observed. The experimental conditions were determined under which the aqueous micellar solutions of a series of rhodamines surpassed the alcohol solutions in lasing sufficiency at a high photostability level. Data are cited which characterize the influence of the named additions in the photobleaching of solutions of certain rhodamines under irradiation by flash lamps.
