Tapered Monolithic Mode-Locked Laser Diode with 200pJ Pulse Energy for Space Applications

To the best of our knowledge, we demonstrate the first mode-locked semiconductor laser reaching 201pJ picosecond pulses without amplifier at low repetition frequency of 2.89GHz, with a very-long (13.5mm) multi-sections tapered laser diode structure, required by European Space Agency for inter-satellite long distance measurements.
