Abstract
A nonimaging beam combiner and collimator. The nonimaging beam combiner and collimator can include at least two light sources that emit light of the same wavelength through a focus point and a nonimaging element that receives the light of the same wavelength after the focus point and collimates the light at the same wavelength through the atmosphere. The at least two light sources can include fiber light sources, optical fibers, gradient index lenses, fiber lasers or laser diodes. The collimator can include an input surface, a paraboloid surface located adjacent to the input surface, a conical surface located adjacent to the paraboloid surface, and an ellipsoid surface located adjacent to the conical surface and located on an opposite side of the collimator from the input surface. The paraboloid surface can include a total internal reflection surface.
