A correction optical element (COE) for a multi-channeled coherent beam combining (CBC) system that uses a fiber array comprising multiple optical fibers and a single collimation array comprising multiple collimating lenses, for coherent combining of a corresponding array of optical beams directed through the fiber array. The COE is configured for customized and segmented correction of collimation-based optical aberrations, caused at least due to misalignments between each corresponding optical fiber's Lij output end and a center of a corresponding collimating lens Lij.

Correction optical elements for coherent beam combining systems and systems and methods for coherent beam combining using same

Aspects of embodiments pertain to beam combining devices for coherent and spectral beam-combining. The coherent beam combining (CBC) device may comprise a monolithic body having an input surface and an output surface. The input surface may be configured to direct a plurality of coherent entering optical beams through an optical pathway inside the monolithic body towards the output surface; and a phase mask configured for combining beams, exiting from the output surface of the monolithic body, to form a single combined output beam. The Spectral beam combining (SBC) device may include a monolithic body configured to direct the entering optical beams through a multi-diffraction optical pathway inside the monolithic body by directing the entering optical beams such as to impinge a diffractive surface thereof at least twice, for combining the entering optical beams into a single multispectral combined output optical beam. Embodiments may also include methods for cascaded beam combining, using multiple combining devices in a network configuration.

Systems, devices and methods for optical beam combining

Embodiments pertain to a system for controlling outputting of light towards objects, the system comprising a detection subsystem configured to detect, for at least one object, one or more values of object characteristics, the object characteristics comprising, at least, electromagnetic absorption characteristics, wherein detection of object characteristic values is performed such that the object remains structurally intact; a light source subsystem comprising at least one light source for generating output light and directing the output light towards an object; and a controller configured to control, based on the detected object characteristics values, at least one operational parameter value of the at least one light source such that at least some of the output light that is directed towards the object has electromagnetic characteristics that correspond to the detected values of the electromagnetic absorption characteristics of the object, in order to structurally change at least part of the respective object.
