Abstract

A simplified approximate expression for the effective nonlinear coefficient of type-II second-harmonic generation in KTiOPO₄ was obtained by observing that the difference between the refractive indices n_x and n_y is 1 order of magnitude smaller than the difference between n_z and n_y (or n_x). The agreement of this approximate equation with the true definition is good, with a maximum discrepancy of 4%.
