OPTICAL PULSES FROM cw GaAs INJECTION LASERS

Abstract

Intensity pulsations of continuously operating GaAs injection lasers have been directly observed for the first time, with fast sampling techniques. The width of the self-induced pulses has been measured to be approximately 390 psec at a repetition rate of 620 MHz. In addition, this pulsewidth has been reduced to less than 200 psec by locking the pulsations with an external modulation of the injection current.
