Efficient uni- and bi-directional oscillations in photorefractive ring resonators
We have demonstrated efficient amplification of 830 nm and 1.06 µm light in a ring resonator using Rh:BaTiO3. The power oscillating inside the ring exceeded the pump power by up to a factor of 2.3 at 1.06 µm. We have also showed that such an efficiently working photorefractive cavity is also sensitive to nanometer changes in its cavity length. We have also observed simultaneous, bi-directional and counterpropagating oscillations in a resonator pumped by a single 647 nm pump beam. The intensity of one oscillation beam was up to two orders of magnitude higher than the intensity of the other oscillation beam.

Abstract

We have demonstrated efficient amplification of 830 nm and 1.06 µm light in a ring resonator using Rh:BaTiO3. The power oscillating inside the ring exceeded the pump power by up to a factor of 2.3 at 1.06 µm. We have also showed that such an efficiently working photorefractive cavity is also sensitive to nanometer changes in its cavity length. We have also observed simultaneous, bi-directional and counterpropagating oscillations in a resonator pumped by a single 647 nm pump beam. The intensity of one oscillation beam was up to two orders of magnitude higher than the intensity of the other oscillation beam.
