Chaotic LIDAR for Naval Applications
Abstract
This report describes the technical progress towards the development of wide-band chaotic lidar technologies designed to provide performance improvements in turbid water. Early in the program Task 1 efforts focused on the feasibility of using the open optical resonator (OOR) approach to produce wideband chaotic laser signals. This task was identified as a precursor to Task 3. Last year we reported that we abandoned the OOR approach in favor of a fiber ring laser approach for several reasons. This effectively allowed us to focus more effort on the more important Task 3. We also reported the development of two infrared (IR) low-power fiber ring lasers that exhibited wide instantaneous bandwidth. Significant progress has been made this past year towards the development of a fiber laser that will satisfy three critical requirements which are 1) an output wavelength m the blue-green; 2) sufficient output power to support underwater experiments; and 3) a chaotic output with an instantaneous bandwidth of at least one gigahertz. To achieve this we adopted a laser design that consisted of low-power chaotic laser source (to achieve the bandwidth), a two-stage fiber amplifier (to achieve high power), and a frequency doubter (to convert from the IR wavelength of 1064nm to a blue-green wavelength of 532nm).
