ABSTRACT:
The transmission line is coupled to a charging circuit and to a series circuit including a terminating resistor, the source and drain electrodes of a MOSFET and laser diode. Trigger signals are applied to the gate electrode of the MOSFET to rapidly discharge the transmisson line to provide currents of about 10 amps through the laser diode to provide pulses of light having durations of about 3 nanoseconds.
