Abstract
We study the second-harmonic (SH) parametric processes
in unpoled crystals of Strontium Barium Niobate (SBN) with disordered
structures of ferroelectric domains. Such crystals allow for the simultaneous
phase matching of several second-order nonlinear processes. We
analyze the polarization properties of these parametric processes using
two types of generation schemes: quasi-collinear SH generation and
transverse SH generation. From our experimental data we determine the
ratio of d32 and d33 components of the second order susceptibility tensor
and also the statistical properties of the random structure of the SBN crystal.
