摘要： 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.

摘要： 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.

摘要： 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.

摘要： Depolarized fiber lasers and respective methods are provided for increasing the SBS (stimulated Brillouin scattering) threshold. The laser source is constructed by a frequency-broadened seed source having a frequency bandwidth of less than 50 GHz, and the depolarization of the seed source is carried out at time scales shorter than 10 ns. At least one amplifier is configured to receive and amplify radiation from the frequency-broadened seed source and deliver the amplified radiation in the optical fiber. Depolarization may be achieved in various ways (e.g., using an interferometer with added length to one arm) and is kept at time scales shorter than tens of nanoseconds, typically shorter than 5-10 ns, which distinguish it from random polarization having polarization changes at longer time scales. Polarization maintaining fibers may be used to further increase the SBS by separating the polarizations states.

摘要： Apparatus for increasing resolution of cryogenically cooled vacuum-sealed infrared imaging detector. A two-dimensional detector array of photosensitive pixels is successively exposed to an image scene, acquiring multiple imaging samples. A masking filter, disposed between the detector array and image scene focal plane, is maintained at a fixed position with respect to the detector array, and reduces the region of pixels collecting incident radiation for each imaging sample such that only a portion of each pixel area of the image scene is imaged onto the corresponding detector array pixel. Shifting means successively shifts the optical path of the image scene relative to the masking filter, by a shifting increment or fill-factor reduction amount equal to a fraction of the array pixel width, to image different sub-pixel regions in each imaging sample. A processor reconstructs an image frame having a resolution greater than the intrinsic detector resolution by the fill-factor reduction amount.

摘要： 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.
