Effect of gamma irradiation on properties of borate glass materials

The final optics of high-power laser facility are exposed to long-period, high-dose gamma irradiation. Being closest to the target, Borate glass is most affected by the irradiation. Therefore, it is very meaningful to study the effects of gamma irradiation on the optical performance and structural properties of borate glass materials. In this paper, the Co-60 source is used as the irradiation source. The borate glass material made in China is irradiated by different doses of gamma ray. The optical performance test and structural properties test are carried out. The results show that gamma ray irradiation has a great influence on the spectral transmittance and surface structure of borate glass. The research results have some guiding significance for the engineering application of borate materials.
