1 September 2004Soliton-like structures in Bi12TiO20 crystal
We present investigations of self-focusing and screening soliton formation processes in photorefractive Bi12TiO20 (BTO) crystals for two different cuts in dependence on both the magnitude of the applied external voltage and additional illumination intensity. We study also temporal behavior of soliton growth and the possibility of stable soliton existence in BTO crystals of the cut [111][112][110].
