Abstract
Low power CO2 laser radars having nominal output powers of 10 watts are currently being developed for a broad spectrum of operational and tactical applications including terrain following, terrain and obstacle avoidance, Doppler navigation, target identification and weapon delivery. No single modulation waveform can perform all of the required sensor functions, but recent advances in modulated waveguide laser technology have made it possible to obtain from a single programmable transmitter such diverse modulation formats as cw output, Q-switched, cavity dumped and RF amplitude modulated waveforms. The intracavity electrooptic modulation techniques used to generate these waveforms in a coherent, frequency stable transmitter will be discussed and both theoretical and experimental modulation formats will be presented. The utility of the various waveforms for particular sensor applications will be considered, along with the impact of laser dynamics on the efficiency of the modulated laser.
