Paper Abstract

Narrow spectral width oscillation of an AlGaInP index-guided diode laser (638 nm) has been achieved with an external stimulated photorefractive backscattering phase-conjugator. The emission spectral width was narrowed down to 5.3 GHz (7.2 pm) due to the very narrow spectral bandwidth of the 2k gratings formed by the stimulated photorefractive backscattering process in a photorefractive barium titanate crystal. The spectral brightness increased approximately 50 times as high as a free-running diode laser. We have also suppressed the self-scanning of the laser frequency, and successfully achieved wavelength-stable oscillation in the phase-conjugator coupled-cavity diode laser.
