The absorption spectra of CuBr, CuCl, CuI, and AgI nanocrystals (NC) embedded in a glass matrix have been investigated in a wide temperature range between T =6 and 860 K. The change of the absorption in the vicinity of the exciton resonance for CuBr

An investigation was made of the kinetics of lasing in neodymium-doped silicate glasses in the form of thin needle-shaped rods with diameters ~ 1 mm and 30–40 cm long. A similarity with fiber lasers was observed. The output radiation included regul
