Patent number: 7113598Abstract: Methods and systems enabling enhanced bit-rate QKD fiber-based key delivery. In one embodiment, a secure communications network of this invention includes a number of communication nodes, each of the communication nodes being connected to a quantum channel. At least one of the communication nodes (a sending node) includes a multiplexing system capable of assembling a succession of substantially single photons in a predetermined order. At least another of the communication nodes (a receiving node) includes a receiving system capable of receiving at least some of the assembled succession of substantially single photons, a demultiplexing system capable of separating the received assembled succession of substantially single photons into a number of separated successions of substantially single photons, and, a number of detector systems, each one of the detector systems being capable of detecting one separated succession of the successions of substantially single photons.Type: GrantFiled: May 13, 2004Date of Patent: September 26, 2006Assignee: Science Research Laboratory, Inc.Inventors: Allen M.

Patent number: 5235239Abstract: Window constructions for use in particle accelerators to separate an evacuated accelerator beam chamber from a gas or liquid filled target area, which window structure enhances cooling of the foil covering the window opening and reduces stresses on the foil. For preferred embodiments, the window opening is shaped and dimensioned to provide high length-to-width aspect ratio and a rectangular shape with rounded corners. The openings should generally be as narrow as possible while still being wide enough to assure efficient transmission of the ion beam. Stresses in the foil is reduced by providing controlled bowing of the portions of the foil covering the window. This may be accomplished by providing some slack in the foil, at least in one dimension, but is preferably accomplished by pressing the foil between mating curved surfaces selectively extending from the edges of the window openings, resulting in the desired bow in the foil in the window area.Type: GrantFiled: June 7, 1991Date of Patent: August 10, 1993Assignee: Science Research Laboratory, Inc.Inventors: Jonah H. Jacob, Allen M. Flusberg, Barbara J. Hughey, Ruth Shefer, Robert Klinkowstein

Patent number: 5021742Abstract: This invention relates to a laser amplifier which achieves substantially enhanced gains by diverging the laser beam in a gain medium having a substantially rectangular shape. In particular, at least one laser beam is passed through a lens or other suitable means to cause it to diverge at a predetermined angle and the diverging beam or beams are caused to pass through the gain medium in a manner such that a beam makes only a single pass through any section of the medium, with the total number of passes through the medium by the beam(s) applied to the medium being an even number. The angle at which the beam diverges should be such as to maintain a near optimum laser power extraction efficiency for the beam. If a single beam is supplied to the medium, it makes an even number of passes through the medium with mirrors, prisms, or other suitable means being provided as the beam exits the medium after each pass except the last pass to fold the beam back into the medium for a subsequent pass.Type: GrantFiled: September 19, 1988Date of Patent: June 4, 1991Assignee: Science Research Laboratory, Inc.Inventor: Jonah H. Jacob

Patent number: 4211983Abstract: Improved electron beam driven gas laser method and apparatus with the achievement of high single pulse energies therefore enabled by establishment of a magnetic field in a direction substantially parallel to the desired direction of electron beam propagation into a gas. The applied magnetic field is made substantially uniform and sized to exceed that of the self induced magnetic field of the current established by the electron beam, alone or in combination with a discharge current (optionally) established in the gas.Type: GrantFiled: May 1, 1978Date of Patent: July 8, 1980Assignee: Avco Everett Research Laboratory, Inc.Inventors: Jack D. Daugherty, Jonah H. Jacob, Joseph A. Mangano

Patent number: 4203078Abstract: Apparatus for and method of operating a laser wherein a discharge is produced preferably in a high pressure lasing gaseous mixture comprising at least one suitable first gaseous species capable of providing an excited state which has a finite probability of being ionized and a molecular second gaseous species having a capability for attaching electrons to form negative ions. The gaseous mixture may, for example, comprise argon, neon, helium, xenon, krypton or a metal vapor such as mercury as the first species and, for example, hydrogen iodide, carbon tetrachloride, bromine, iodine or fluorine as the second species. A buffer gas such as, for example, argon, helium or neon may also be used. The discharge is produced by means of an electron beam and an electric field. The discharge resulting from the application of the electric field heats secondary electrons produced by the electron beam to an energy level sufficient to make excited states.Type: GrantFiled: May 6, 1977Date of Patent: May 13, 1980Assignee: Avco Everett Research Laboratory, Inc.Inventors: Jack D. Daugherty, Jonah H. Jacob, Joseph A. Mangano
