Power scalable, rectangular, multi-mode, self-imaging, waveguide technologies are used with various combination of large aperture configurations,, Gaussianand super-Gaussianbeam profiles, thermal management configurations, flaredand taperedwaveguide shapes, axial or zig-zag light propagation paths, diffractive wall couplersand phase controller, flexibility, phased arrays, beam combiners', and separators, and other features to generate, transport, and deliver high power laser beams.

Power scalable optical systems for generating, transporting, and delivering high power, high quality, laser beams

The present invention is directed to guided wave systems, beam transport and waveguide techniques. The invention may comprise passive or active, hollow and dielectric core self-imaging mode wave guide systems, beam amplifiers (), laser resonators (), beam transports, and waveguides. Embodiments may include rectangular cross-section waveguides, and preferably maintaining spatial profile of an input beam, such as a Gaussian beam, through the self-imaging period of the waveguide while unique new capabilities to mitigate non-linear distortions that corrupt spatial, spectral and temporal coherence and polarization. Additional aspects may include, for example, transport, amplification, phase/frequency control or modulation, deflection, conversion, synthetic aperture, distributed aperture, beam forming, beam steering, beam combining, power sampling, power combining and power splitting, among other features. Some embodiments may provide a self-imaging, multimode, waveguide () and self-imaging guided wave systems and beam transport. Embodiments of the present invention may further provide a method of self-imaging, multimode beam transport and other self-imaging wave guidance techniques.
