| Abstract: | An analytical function involving four parameters is proposed to express the second-harmonic generation efficiency as well
as the parametric generation gain coefficient in the Boyd–Kleinman theory. The analytical function clearly reveals the dependence
of conversion efficiency on the focusing parameter and the walk-off parameter. Moreover, the optimum focusing parameter and
its corresponding maximum efficiency are explicitly given in the analytical function, leading to a straightforward evaluation
of a given crystal performance.
