Abstract

We present several new characteristics of beam fanning in a bulk sample of Bi₁₂SiO₂₀ with a dc electric field applied to it. Significant dependence of the beam fanning on the polarization state of the incident laser beam is observed. Moreover, the fanning light experiences a spontaneous frequency shift with respect to the incident light that ensures maximum beam coupling, because of which the fanning itself can exist.
