Chaotic LIDAR for Naval Applications

Abstract

A 532 nm chaotic laser (CLASER) transmitter was developed to investigate the performance of wideband chaotic lidar (CLIDAR) for naval underwater applications. The transmitter was built using a frequency doubled infrared fiber laser. Multiple fiber laser architectures were studied, built, and tested. A novel ultralong cavity (~100m) ring resonator was implemented for its noise-like chaotic intensity modulation. This laser generated wideband intensity modulation in the laser itself and did not require a separate optical modulator or RF signal source. The final configuration produced two hundred milliwatts of power at 532 nm with > IGHz of noise-like chaotic intensity modulation bandwidth.
