Production of short pulses in semiconductor lasers by external laser excitation through chi((3)).
It is shown that parametric mixing through chi((3)) of two injected laser lines can provide index modulation sufficient for the mode locking of the semiconductor laser. Numerical estimates indicate that picosecond pulses with 100-GHz repetition rates should be possible with a few watts of external laser power.
