Abstract
Previous reports of harmonically driven mode-locked semiconductor lasers have indicated that the intensity correlation between adjacent pulses has a contrast ratio of two, rather than three as expected for mode-locked pulses. We show that this reduced contrast ratio is a result of pulse instabilities in harmonically driven mode-locked lasers. By setting the rf drive frequency to the stable operating condition, stable pulses with a contrast ratio of three have been obtained.
