Photoinduced optical effects in BiB3O6 glass

A new borate material, BiB3O6 (BiBO) has been reported to have extremely high nonlinear optical (NLO) coefficient. In our investigations we obtained both glass and single crystal of BiBO. Owing to its composition, the material is very viscous when molten. This factor cause serious problems both during synthesis and crystallization of BiBO. In this paper only properties of BiBO glass are reported. We found that for the increase of the long-range ordering the photoinduced optical second harmonic generation (SHG) shows a maximum, which is shifted towards the lower photo inducing power with the increase of the temperature. Maximal value of SHG was about 0.081 pm/V at 1.06 micrometers radiation from YAG:Nd laser.
