Abstract :
The linewidth and side-mode suppression ratio of three variable-gap C3 lasers were measured as a function of output power and drive currents. With feedback carefully eliminated, the narrowest linewidth obtained was 8 MHz at an output power of 13.6 mW. There was little correlation between line-width and suppression ratio.
