1. A source of phase-stable optical pulses, comprising;
- a modelocked fiber laser;
a multi-core fiber amplifier comprising an array of individual fiber amplifiers arranged so as to amplify an output of said mode locked fiber laser, said individual amplifiers being configured to produce said individual outputs;
at least one phase sensor to detect the phase of outputs of said individual amplifiers; and
at least one phase stabilizer to stabilize the phase of said individual amplifiers, said stable phase being obtained at the output of said fiber amplifier array, said stable phase being characterized in that the relative phase fluctuations between individual amplifiers is smaller than 1 rad.
