Effect of incoherent illumination on two-beam interaction of light waves in a bismuth titanate crystal

Experimental investigations and theoretical analysis of the effect of external illumination on the dynamics of formation of photorefractive reflection gratings in a (100)-cut bismuth titanate crystal showed that, in the case of counter interaction of laser beams with a wavelength of 633 nm, incohere...

Description
Summary:Experimental investigations and theoretical analysis of the effect of external illumination on the dynamics of formation of photorefractive reflection gratings in a (100)-cut bismuth titanate crystal showed that, in the case of counter interaction of laser beams with a wavelength of 633 nm, incoherent green light may cause a change in the sign of the two-beam gain.
