Abstract
We report the first demonstration, what is to our knowledge, of resonant second harmonic generation using a photorefractive phase conjugate feedback. Once the phase conjugator turns on, the SH output form self-frequency- doubled NYAB laser starts to increase and reaches up to 9-10 times of that without feedback. In addition, we find that the SH output fluctuates even if the phase conjugate feedback is constant. This phenomena is induced by the self- frequency-scanning of the SH output.
