Abstract :
AlGaAs d.h. lasers with relatively low d.c. bias were demonstrated to be quite feasible for generation of a train of 30 ps optical pulses at a modulated frequency of below the GHz range. The pulse envelope width was measured by an s.h.g. correlation method as well as an ultrafast streak camera; the results agreed fairly well.
