Energy characteristics of non-resonator generation in nanodispersion active media under irradiation by femtosecond laser pulses
The experimental results of measuring the energy characteristics of stimulated emission in solutions of coumarin-30 and rhodamine 6g dyes with nanoparticles upon irradiation with femtosecond laser pulses are presented. It is shown that for single-photon absorption, the stimulated emission thresholds are two orders of magnitude lower than for two-photon absorption.
