Abstract
An optical arrangement comprising first and second guided structures for providing first and second beams of electromagnetic energy and a node for coherently combining said first and second beams in free space, that is, with an unguided structure. In the illustrative embodiment, the first and second structures are first and second fiber oscillators. The first and second fiber oscillators may be of unequal lengths. The node may be implemented with a polarizing beam splitter or a semi-reflective surface. Beam shaping optics are included in the node to collimate the first and second beams and provide a flat profile mode thereof. The outputs of plural first and second fiber oscillators are combined via plural nodes to provide a single high energy output beam. Amplifying elements may be disposed between nodes. The plural nodes may be disposed in a single integrated structure along with an outcoupler mirror to coherently phase lock the outputs of the plural oscillators.
