Patent
·
OSTI ID:7295788
This patent describes an apparatus for providing sub-microsecond light pulses in response to a control signal. It comprises transmission line means for storing electrical energy provided thereto prior to the control signal, and having a characteristic impedance between first and second output conductors thereof; resistive means having an impedance; a light emitting device having impedance in the on state; and a three terminal switch having a control terminal and current conducting terminals; and wherein the resistive means, the light emitting device and the switch are serially coupled between the first and second output conductors of the transmission line means.
