Abstract
The properties of stimulated emission of Ph160 dye in the pores of PAO were studied. The quantum yield of fluorescence was Ff = 0.73. Stimulated emission of Ph160 molecules in the pores of alumina was obtained at the maximum of fluorescence band. The threshold of stimulated emission was 1.7 MW/cm2. It is shown that low-Q generation of stimulated emission in the film Q≥ 1 * 102 relates to the fact that the ray geometry of in the pores is not approximate to the ray geometry for the case of total internal reflection, resulting in the increase of radiative losses. The presence of gold nanoparticles in PAO results in the increase in fluorescence intensity and lowering of the generation threshold of dye stimulated emission.
