Paper Abstract

Spectral control of a commercial laser diode with a self-pumped phase conjugation (SPPC) feedback from a Ce:BaTiO3 crystal was experimentally investigated. A SPPC reflectivity of as high as 65% was obtained at a 1mW incident power and a 782 nm central wavelength. The laser spectrum strongly depends on the reflectivity and length of the external SPPC cavity. The external reflectivity should be in a range of 0.1 to approximately 0.6% for our experimental setup to obtain a narrowed linewidth.
