Optical pulses at a repetition frequency of 1 GHz from a gainswitched InGaAsP distributed‐feedback laser diode at 1.3 μm are optically sampled with compressed pulses from a mode‐locked erbium‐doped fiber laser amplifier. High signal‐to‐noise ratios down to 21‐μW average laser‐diode power with temporal resolutions close to the sampling pulse duration of 4 ps are achieved. The sampled waveform is displayed at a repetition rate of 3 Hz or higher to give a real‐time measurement.
