Abstract: 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 objec

Abstract: 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.
