Paper Abstract

The spectral dependencies of the optical rotatory power (ORP) and Verdet coefficient (V) of undoped Bi12GeO20 (BGO), Bi12SiO20 (BSO) and Bi12TiO20 (BTO), and doped with V, Fe and Cr BSO crystals are studied. It is established that Cr and Fe strongly change ORP and, respectively, V in BSO in a wide spectral range from 480 to 1180 nm. Thus an increasing of ORP by about 92.8% at 480 nm, 25.3% at 756 nm, and 5.2% at 1171 nm, is observed in BSO:Cr. The dopant Fe in BSO strongly increases the Verdet coefficient V in the whole studied range -- with about 80 -- 300%, as at the longwaves an anomalous considerable increasing of V is observed. On the contrary, Cr and Fe decrease V and ORP, respectively. Using a fiber-optic system, the local ORP and V are measured. Some differences in ORP and V are observed within and without the so-called `central core.' A good qualitative evaluation of the local impurities and dopants distributions within and without the core could be based on these differences.
