ABSTRACT:
The present invention provides three embodiments of circuitry, responsive to the application of an energizing pulse to the high pressure tube of a hybrid laser, for de-energizing the normally continuously energized low-pressure tube of the hybrid laser for only a given time interval which is longer than the duration of the high-energy pulse of coherent wave energy generated by the high pressure tube when energized. This solves a prior-art problem of sporadic spike emissions by the low-pressure tube during the time interval in which echoes from objects of interest are being received by a LIDAR employing a hybrid laser transmitter portion.
