Abstract:

This paper presents the results of study of the radiation stability of LiB3O5 (LBO) crystals with regard to optical properties. LBO crystals of the high optical quality were studied under action of an electron beam with energy of 0.2-10 MeV, X-rays, and polarized synchrotron radiation of a high intensity. Both the trapped electron (B2+) and hole (O-) centers were revealed and their optical manifestations were studied in detail. In particular, the strong radiation-induced optical absorption band at lambda = 306 nm, extending up to the spectral region of the second harmonic (at about 532 nm), was attributed to the optical transitions inside the O- center. The accumulation of defects over the dose region between 10(10) and 5x10(16) electrons per cm(2) was measured. The accumulation curve at 77 K exhibits two well-defined flux regions: 10(10)-10(14) and 10(14)-10(16) electrons per cm(2). The paper discusses the origin of radiation degradation of LiB3O5 optical properties.
