Abstract
A significant narrowing of the longitudinal-mode spectrum of continuou s-wave visible gain-guided diode lasers was achieved by using an exter nal cavity bounded by a phase conjugate mirror. Longitudinal-mode disc rimination was further improved by inserting a thin etalon in the exte rnal cavity. With this technique, the coherence length of the laser be am has been increased by a factor of 4 and the emission wavelength was tunable over a range of 1.4 nm, at constant temperature.
