Phosphate neodymium glass for laser use

摘要

Phosphate neodymium glass for laser use, consisting of phosphoric anhydride, an oxide of at least one of alkaline metals, and neodymium oxide or a mixture of neodymium oxide and oxide of at least one of the following metals; La, Gd, Lu, Sc, Y, Al, Cr; the ratio between the above-cited components as follows (mol. %): -phosphoric anhydride 64-77 -oxide of at least one of alkaline metals 26-8 -neodymium oxide or a mixture of neodymium 10-15 -oxide with an oxide of at least one of the -metals: Ln, Gd, Lu, Sc, Y, Al, Cr. - The herein-proposed invention is intended for producing active elements for lasers of a wide purpose including thin-film and miniature lasers with generation wavelengths within the ranges 1.06 and 1.34 mu . Phosphate neodymium glass for laser use of the developed composition can be synthesized in required amounts by a simple method. Application of this glass for making active elements of lasers leads to increasing the efficiency of pumping and specific power output.
