A 10 GHz mode‐locked fibre laser has been treated to improve its stability and the quality of generated pulses. An unpumped 3 m erbium‐doped fibre (EDF) is incorporated outside the cavity at the output of the mode‐locked laser and a setup is designed so as to form the strong standing waves inside the EDF that leads to spatial hole burning effect. This reduces the phase noise of the mode‐locked laser, resulting in the timing jitter reduction from 260 to 130 fs.
