The effect of the facet reflectivity on the linewidth of a single-frequency (GaAl)As diode laser has been studied by measuring the linewidth as a function of the laser output power before and after a high reflectivity coating was applied to one facet of the laser. The observed linewidth reduction arising from the increase in the cavity Q agrees with predictions of linewidth theories. The results indicate that the application of high reflectivity coatings can be a practical method for achieving a substantial reduction of the linewidth of (GaAl)As diode lasers.
