Spectra of formation of color centers in laser glasses

An investigation was made of the spectra of formation of color centers in industrial silicate glasses. These centers were formed by ultraviolet radiation in a narrow band ~15 nm wide in the range λ = 180–240 nm. A correlation was found between the position of the short-wavelength absorption edge of a glass and the position of the spectrum of formation of color centers. The action of the usually employed antlsolarizers reduced mainly to the absorption of the photochemically active radiation of λ = 180–240 nm wavelengths.
