Abstract
The present invention provides an apparatus and method for free space optical communication. The apparatus includes a first optical source configured to generate a first optical beam, a first optical beam carrier optically aligned with the first optical source and configured to propagate at least a portion of the first optical beam, and an extended source optically aligned with the first optical beam carrier and configured to output an extended source optical beam. The extended source can include an extended source telescope configured to direct at least a portion of the first optical beam to output the extended source optical beam into free-space. Alternative the extended source can include a large core fiber optic cable configured to propagate at least a portion of the first optical beam exercising additional modes of the large core fiber cable to generate the extended source optical beam.
