Abstract

A pulsed, modulation frequency tunable, frequency-doubled Nd:YAG laser has been devised for use in target detection through turbid media. A modulated pulse laser radar system offers many advantages in target detection, such as significant signal contrast enhancement, compared with conventional remote-sensing systems. By implementation of the dual-longitudinal-mode seed injection technique, the modulation frequency of the designed Q-switched laser can be tuned from 250 MHz up to 60 GHz in steps of 250 MHz while maintaining a modulation depth of at least 75%. This provides the ability to explore propagation and scattering properties further at previously unattainable high RF modulation frequencies.
