Abstract

Properties of stimulated emission of Rhodamine 6 G in porous alumina matrix have been investigated. The characteristics of stimulated emission were examined upon excitation of the samples by second harmonic of Nd: YAG laser in the longitudinal form. It is established that when the pumping source power is equal to 0.38 MW cm-2 on the background spectrum of laser-induced fluorescence the narrow strip of the stimulated emission with a peak wavelength of 566 nm appears. Further increase in the power density of the pumping source leads to a narrowing of the band of stimulated emission and an increase in its intensity. The presence of silver NPs in porous alumina lowers the threshold of stimulated emission of the dye.
