A self-consistent theory is used to derive the frequency shift presented by the oscillating
mode in a cavity that contains a photorefractive crystal. A long-time-limit theory has been …

In a cavity with photorefractive gain the resonator field is fed by a pump beam through two-
wave mixing inside a photorefractive crystal. In this paper we develop a simplified model for …

A theoretical analysis of the oscillator with a photorefractive gain is presented. The steady
multimode oscillation is considered. In such a system, the cavity light beam undergoes a …

The steady-state amplification of light beam during two-wave mixing in photorefractive
materials has been analysed in the strong nonlinear regime. The oscillation conditions for …

Oscillation conditions for unidirectional ring resonators containing cubic photorefractive
crystals are analyzed. The coupling of pump beams to intracavity modes is presumed to …

The dynamics of a photorefractive oscillator has been studied in the weakly multimode case.
It is shown that the eigenmodes of the empty cavity provide the bases in which the …

Photorefractive resonators exhibit an extremely small frequency difference (Δω/ω~ 10^− 15)
between the oscillating and pumping beams. The observed frequency difference is …

We have constructed an optical resonator using a photorefractive crystal as the gain
medium. The orientation of the crystal and the angle between the signal and the pump beam …

The basic phenomena of transverse dynamics of a two-wave mixing photorefractive
oscillator (PRO) in the weakly multimode case are considered. The evolution of the …

We present a theory of the frequency-detuning properties of various oscillators formed by
four-wave mixing in photorefractive crystals. It is shown that the detuning originates from the …
