The spectral and lasing parameters of solid laser elements made of a nanoporous glass — polymer composite doped with phenalemine dyes are studied. A high conversion efficiency (35%— 40%) of second-harmonic nanosecond pulses from a Nd3+:YAG laser to the 600 — 660-nm region was obtained and a large operating life of the laser elements was demonstrated. A comparison of the parameters of solid laser elements with those of the liquid solutions of the same dyes showed that the conversion efficiency in solid laser elements is as good as that for the dye solutions.
