We report the measurement of electric field correlations of a hybridly modelocked external linear cavity semiconductor laser as a function pulse delay. We also report the measurement of residual phase noise corner frequency and longitudinal mode linewidth as a function of laser cavity length. We find that the pulses in the modelocked pulsetrain are correlated at only multiples of the cavity roundtrip time. Excellent agreement between residual phase noise corner frequency and longitudinal mode linewidth measurements suggest that the corner frequency is the average longitudinal mode linewidth. This relationship leads to a fundamental limit in the timing jitter of modelocked lasers.
