Abstract: A system and method for analyzing quality criteria of a radiation spot are provided herein. The system may include: at least one controllable electromagnetic radiation source configured to generate and transmit a radiation beam onto an object, resulting in a radiation spot on said object; at least one radiation sensor configured to sense and obtain radiation reflections coming back from said object, wherein the radiation beam is generated in a way that reflections from different ranges are distinguishable of each other; and an analyzer configured to analyze said radiation reflections, and determine a remedy to the radiation beam, in a case that said radiation spot does not meet predefined spot validity criteria. The method may implement the aforementioned logic in a different architecture.

Abstract: 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.

Abstract: Multi-Channels coherent beam combining (CBC) using a mechanism for phase and/or polarization locking that uses a reference optical beam and an array of optical detectors each detector being configured and located to detect overall intensity of an optical interference signal caused by interfering of the reference beam and a beam of the respective channel, where the fast intensity per-channel detection allows simultaneous and quick phase/polarization locking of all channels for improving beam combining system performances.

Abstract: In some embodiments, a catadioptric optical system (CDOS) including a centrally obscured reflective telescope is disclosed, which includes: a telescope compartment defining a telescope space therein, a primary reflector including a central opening and a secondary reflector. The reflectors are located in the telescope compartment. The CDOS also includes a mechanism for reducing temperature gradient in the telescope space. The mechanism includes an air duct including a first opening and a second opening; a hollow enclosure including side openings and one or more airflow generation devices. The mechanism is configured for forming an air passageway between the airflow generation device and the inner telescope space via the air duct and hollow enclosure located therebetween, for reducing internal air temperature gradient in the telescope space.

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. Embodiments may also include methods for cascaded beam combining, using multiple combining devices in a network configuration.
