Patent number: 10890417Abstract: The Compound Eye Laser Illumination Seeker (CELIS) is a tracking system used to guide items to point at a laser-illuminated target, with the illumination being either pulsed or modulated at either a specific rate or within a range of rates. The CELIS, comprising a multiaperture compound receiver optics (MACRO) to collect the signal, a set of light guides to combine the received light into light representing individual angular sectors and redirect it to detectors whose output represents the illumination signal in that quadrant, a spectral filter, an angle filter, the set of detectors, and processing electronics. The output is an electronic signal indicating the angular difference between the pointing direction of the signal and the pointing direction of the tracking device.Type: GrantFiled: May 7, 2019Date of Patent: January 12, 2021Assignee: LUMINIT LLCInventors: Jun Ai, Fedor Dimov, Russell Kurtz, Emmanuel Gorce

Patent number: 10281391Abstract: A laser system containing an etalon to reduce the spectral bandwidth and for tuning, with cavity dumping to generate the short pulses is described. The resulting system is stable and not overly complicated. The combination of cavity dumping with an intracavity etalon enables the invention to produce a string of short pulses, each of which has a very narrow spectral bandwidth. Tuning the wavelength over a spectral range that is very small, but much larger than the laser's spectral bandwidth, enables the invention to use dual-wavelength lidar, DIAL, differential spectroscopy, or a combination of these methods to measure the concentration of the desired chemicals with excellent accuracy.Type: GrantFiled: June 2, 2016Date of Patent: May 7, 2019Assignee: LUMINIT LLCInventors: Russell Kurtz, Alkan Gulses

Patent number: 9920447Abstract: A graphene composite coating on a metal surface with excellent corrosion resistance by electrophoretic or electrolytic deposition has been obtained. The composite coating was shown to significantly increase the resistance of the metal surface to electrochemical degradation. The graphene coating significantly reduces cathodic current, which is an indicator of the rate of corrosion at the interface between the cathodic material and the anodic material.Type: GrantFiled: August 20, 2015Date of Patent: March 20, 2018Assignee: LUMINIT LLCInventors: Russell Kurtz, Mark Bennahmias

Publication number: 20170365974Abstract: A short-pulse, narrowband, line-selectable and tunable solid-state laser is described. The device requires a pump source, an active solid-state laser medium, an enclosing cavity, mirrors to contain the light, a method of removing the pulse from the cavity, a wavelength selection system, and a laser linewidth narrowing system. One implementation of this is an Er:YAG laser, side pumped by semiconductor lasers in the erbium absorption band near 1475 nm, with an intracavity etalon and a switchable spectral filter. To remove the pulse from the cavity, cavity dumping issues, which assures constant pulse energy and pulse length over a range of repetition rates, in this case from 100 Hz to 20 kHz. Line selection is obtained by use of wavelength filters and fine tuning with an etalon, which also acts as the linewidth narrowing system.Type: ApplicationFiled: June 15, 2016Publication date: December 21, 2017Inventors: Russell KURTZ, Alkan GULSES
