Influence of photoconductivity and dielectric constant on an oscillation characteristics of a photorefractive resonator

In the present paper, photoconductive and dielectric dependence oscillation characteristics of a single photorefractive ring resonator have been studied for the case of non-degenerate two-wave mixing in photorefractive materials by employing the plane-wave approximation method. The influence of photoconductivity and dielectric constant of photorefractive materials on frequency of oscillation and the intensity of oscillating beam inside a single photorefractive ring resonator have been explored in details. It has been found that for a photorefractive material of fixed value of dielectric constant, the intensity of oscillation decreases more rapidly with the increasing frequency detuning of the resonator which means that the constant region of the intensity of oscillation could be extended by keeping the frequency detuning ( Hz 0 . 1   ) of the resonator as low as possible. This means that the fall in the intensity of oscillation can be reduced by keeping the frequency detuning ( Hz 0 . 1   ) of the resonator as low as possible.
