Method for determining the laser stability of optical material

摘要

The method involves determining an induced non intrinsic fluorescence. The induced fluorescence directly activated after pre radiation and after 10 minutes after the end of the pre-radiation with light of a wavelength between 350-700 nanometers. The intensity of this fluorescence is determined between 550 and 810 nanometers and evaluated quantitatively with one or more wavelengths within the range.
