Second order nonlinear optical polarization P(2) has been calculated theoretically for several crystals having zinc-blende symmetries. Three distinct wavelengths 457 nm, 488 nm and 514 nm emitted from a continuous wave (cw) Ar-ion laser have been considered for the estimation of the second order nonlinear optical polarization. The study reveals nonlinear dependence of the second order nonlinear optical polarization on the applied electric field intensities at various wavelengths.
