Abstract

We analyze the applicability of a number of exponent-type phenomenological kinetics for transmission degradation prediction in commercial optical glasses during and after irradiation. The analysis is based on post-radiation transmission measurements over a 5 years time interval of a commercial boro-silicate glass (BK7, Schott). A conclusion is drawn that the choice should be made between the stretched-exponential and the multi-exponential functions. We apply those kinetics to simulate kinetics of BK7 glass transmission spectra subject to Co⁶⁰ gamma-radiation in the framework of the previously developed phenomenological model. Calculated transmission spectra agree well with our experimental data.
