Abstract
Methods and systems for using a laser type clock to produce a train of ultra-stable optical pulses. The methods and systems include generating an approximately 10 GHz ultralow noise pulse train from a harmonically modelocked laser having an intracavity Fabry-Perot etalon filter from a semiconductor lasers such as ring lasers, and the like. System output can have residual phase modulation(PM) noise values of approximately 18 fs and amplitude modulation(AM) noise values of approximately 0.05% RMS, and residual phase modulation(PM) noise values of approximately 94 fs and amplitude modulation(AM) noise values of approximately 0.05% RMS.
