Abstract
A method of driving a multimode laser diode has pulse circuitry providing a sequence of drive current pulses to the laser and modulation circuitry superimposing a modulation current upon the drive current pulses. When the modulation amplitude and rate are sufficiently great, rapid switching of transverse modes of laser operation is induced during each laser pulse. The effect of many different modes is averaged out so that the observed light output, even in a high power apertured system, is stable both within a single pulse and from one pulse to the next.
