Abstract :
We present the first observation, to our knowledge, of photorefractive screening solitons in BaTiO3 and study the effects of a tilted crystalline orientation in such a zero-cut n-type crystal. We examine on-axis lD soliton propagation by cylindrically focusing a 515 nm laser beam and launching it along a crystalline a-axis and having it polarized parallel to the c-axis (extraordinary polarization)
