Abstract :
We investigated the second harmonics generation when a constant gradient of the wave-number mismatch was imposed along a nonlinear crystal. Behavior of the complex amplitude of the second harmonic signal was geometrically visualized by means of the Cornu spiral. Phase-matching bandwidths and conversion efficiencies of the second harmonics generation in low-conversion approximation with and without wave-number mismatch gradient are compared.
