The above equations include Fresnel transmission and reflection coefficients of the
fundamental and second-harmonic fields. For example, tsOl (w o ) is the Fresnel transmission
coefficient for s-polarized light from layer 0 to layer 1. The Fresnel reflection
coefficient is denoted similarly with T substituted for t. Equation (6.25) explicitly displays
the three factors on which the nonlinear response of the media depends. These
