Paper Abstract

We present what is, to our knowledge, the first report of a single-mode operation of broad-stripe LD using a photorefractive phase conjugator as an external cavity mirror. A single-longitudinal-mode operation of a 190 mW broad-stripe LD with 0.2 nm line-width could be obtained using an external semi-linear type phase conjugate mirror. Its wavelength was locked at 805.5 nm within 0.02 nm over 20 minutes. Further, by varying a LD's temperature, its lasing wavelength could be continuously tuned in the range between 802 nm and 809 nm.
