We study the delay-time statistics of femtosecond pulses generated from GaAs/AlGaAs multiple contact heterostructures under the superradiant (SR) emission generation. The turn-on time of superradiant pulses was measured by a single-shot streak camera with a few picoseconds temporal resolution using low-jitter reference pulses. The fluctuations of the delay times of SR pulses were found to be by more than one order of magnitude larger as compared to standard lasing and a few times larger than for SR emission from other types of media.
