We investigate the temperature dependence of second harmonic generation in order-disorder ferroelectrics. We obtain the qualitative temperature dependence of the second harmonic amplitude; the amplitude goes to zero when the temperature reaches the Curie point. We take into account the disruption of wave number harmony when the temperature is changed. We show the second harmonic is largest at the temperature where the wave numbers are synchronized and there is no detuning. The theoretical conclusions reached here are confirmed by experimental data.
