Still, for quick design, phase matching, and comparison of crystals, SNLO is invaluable.
Periodically inverting the orientation of the crystal domains (period Λcap lambda ) every time the waves slip out of phase by 180∘180 raised to the composed with power . This introduces a grating vector to reset the phase: crystal nonlinear optics with snlo examples pdf
