Chaotic LIDAR for Naval Applications

Abstract

Two fiber ring lasers have been developed to date. Both were described in Progress Report 004; one is a 1550 nm source based on erbium (Er) doped fiber which was constructed as a proof-of-concept laser. The other is a source based on ytterbium (Yb) doped fiber which will be frequency doubled to the blue-green wavelength required for underwater experiments. Characterization of the Yb fiber laser has been performed this period. We also have further investigated the dynamic behavior of the modes that make up the laser output. We are currently investigating two signal autocorrelation-based signal processing techniques. The first is an analog approach based on a coherent noise detection (CAND) approach that was originally proposed for noise radar. We are also investigating a digital signal processing (DSP) approach based on a software defined radio architecture.
