摘要：
Results of experimental measurements of the energy characteristics of stimulated emission in coumarin-30 and rhodamine 6G dyes with nanoparticles under irradiation with femtosecond laser pulses are presented. It is shown that the stimulated emission thresholds of the active medium with one-photon absorption containing nanoparticles are by a factor of 1.4 lower than of the pure active medium.
