Start-up and stabilization of mode-locked lasers

Methods and systems for controlling start-up and stabilization of mode-locked lasers are disclosed. A laser stabilization method may include: receiving a laser beam generated by a mode-locked laser; generating a current based on the laser beam received, wherein the generation of the current generates a radio frequency (RF) waveform; amplifying the RF waveform to a level suitable to be processed by a mixer communicatively coupled with the mode-locked laser; and adjusting a phase of the amplified RF waveform to compensate for effects of environmental changes on the laser beam generated by the mode-locked laser.
