An optical intensity correlation measurement is carried out on the recovery of saturable absorber (SA) in an modelocked semiconductor laser diode (MLLD) device in picosecond temporal regions. Optical pulse train of few picosecond with repetition rates of up to 10 GHz is used to provide direct information on the SA response to high-repetition optical pulses as occurs in actual modelocking operation. The shortest recovery time observed was 8 ps at a reverse bias of 2 V. Short recovery times at a large reverse bias are consistently observed over a wide range of pulse repetition rates and optical pump energies. The results showed that the fast SA recovery in the picosecond range takes place in actual modelocking operation.
