The repetition frequency of an external cavity mode-locked GaAs semiconductor diode laser has been stabilised by voltage controlled electrical feedback. The phase noise has been reduced by 40 dB at 1 kHz offset from the carrier and timing jitter reduced from more than 30 ps to 4 ps. This technique can be used to stabilise millimetre-wave mode-locked lasers.
