Temperature dependence of a resonator with two doped-LiNbO3 phase-conjugate mirrors

The temperature-dependent intensity formulas about the optical resonator with two phase-conjugate-mirrors (PCM) are bult up by using a band transport model and the coupling wave equa tion under the strong pumping condition in steady state. For PCM, there is a optimum temperature value and the resonator has the maximum output light power when the temperature is equal to the value.There are different optimum Pump ratio for PCMs under different temperature. In the experimental system, the optical ramator contains two PCMs made with Ce:LiNbO3 single crystal and a He-Ne laser.The experimental results are in agreement to theoretical analysis.
