Study of the spectral composition of the radiation of the neodymium-glass laser with combined active medium

A method for obtaining a broad (30–100 Å) emission line in neodymium-glass lasers is proposed. In this case, an active medium is a combination of two different glass matrices, silicate and phosphate, doped with Nd3+ ions. The structure and spectrum width of such lasers were experimentally studied depending on the active element properties, cavity type, and pump power. A radiation spectrum width more than twice larger in comparison with silicate-glass lasers was achieved.
