摘要: The method determines the extent of irreversible radiation damage an optical material. includes following three tests to determine damage: 1) material is irradiated with ultraviolet at a wavelength 193 nm and non-intrinsic fluorescence intensity 740 measured; 2) high energy laser light change in respective absorptions 385 determined before after irradiation; 3) energetic source form all possible color centers difference surface integrals corresponding absorption spectra spectral and/or visible regions measured irradiation.
