Study of active media on nano- and microparticles of solid-state laser materials

Prospects of active media based on nano- and microparticles of laser crystals and glasses are discussed. Study on laser beams propagation over the index-matched mixtures of solid microparticles with liquids and results of experiments on pumping and lasing in active media with microparticles of Nd-doped glasses and fluoride crystals will be reported.
