Abstract

It is known, that the application of chromium ions for the effective sensitized luminescence of rare-earth ions in crystals with garnet structure has allowed to solve a number of problems in physics and technology of solid-state lasers. So, for example, the efficiency of pulsed neodymium lasers has been increased 2-3 times . and effective lasing on both erbium2 (=2.79 pin) and golmium (A,=2.088 pin) transitions with low probability was obtained. The possibility of sensitization has a principle character for erbium and golmium ions due to rather low pump efficiency into its absorption bands. It should be mentioned that the interest to 2-pam and 3-pin lasers especially increased whn5 the possibility of their medical application was demonstrated
