Patent number: 9246295Abstract: A high power ultrashort chirped pulse amplifier laser system, with a chirped pulse amplifier laser module including an optical pulse stretcher, at least one optical power amplifier, and an optical pulse compressor, and a beam interferometer module in the optical path. The beam interferometer receives splits the pulse into at least two pulses, adds a time delay to at least one of the pulses and recombines the pulses to produce a temporally modulated pulse. The resulting modulated output pulse from the CPA laser module can have enhanced laser contrast due to greatly reduced subpicosecond pedestal in the immediate region of the peak pulse, or can have other desirable characteristics.Type: GrantFiled: November 24, 2014Date of Patent: January 26, 2016Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Dmitri Kaganovich, Joseph R. Penano, Michael H. Helle, Antonio C. Ting, Daniel F. Gordon, Bahman Hafizi

Patent number: 9088123Abstract: A method for generating an extended underwater plasma. A first laser pulse is fired into a body of water to form an underwater optical filament coinciding with a low-energy plasma. A second laser pulse is fired into the water, targeted at the plasma. The second pulse heats the plasma, causing the formation of an extended superheated plasma volume in the water. The two laser pulses can be simultaneous or can be sequential, with the second pulse following the first pulse by up to the filament plasma lifetime. The extended superheated plasma creates an underwater acoustic pulse, wherein the duration, waveform and directivity of the pulse can be tailored by controlling the shape of the underwater laser-generated plasma.Type: GrantFiled: December 12, 2012Date of Patent: July 21, 2015Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Theodore G. Jones, Antonio C. Ting, Daniel F. Gordon, Michael H. Helle, Joseph R. Peñano

Patent number: 8665923Abstract: A laser pulse from an ultrashort pulse laser (USPL) is fired into the atmosphere. The USPL pulse is configured to generate a plasma filament at a predefined target in the atmosphere, in which free, or “seed,” electrons are generated by multi-photon or tunneling ionization of the air molecules in the filament. A second pulse is fired into the atmosphere to form a heater beam that impinges on the plasma filament and thermalizes the seed electrons within the plasma filament, leading to the collisional excitation of the electrons in the filament. The excited electrons collisionally excite various electronic and vibrational states of the air molecules in the filament, causing population inversions and lasing, e.g., exciting the C3?u?B3?g(v=0?0) transition of the N2 in the atmosphere to cause lasing at 337 nm.Type: GrantFiled: December 22, 2011Date of Patent: March 4, 2014Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Phillip A. Sprangle, Joseph R. Penano, Marlan O. Scully, Daniel F. Gordon, Bahman Hafizi

Patent number: 8564224Abstract: An electron injector including an electron source and a conducting grid situated close to the electron source, one or more RF accelerating/bunching cavities operating at the same fundamental RF frequency; a DC voltage source configured to bias the cathode at a small positive voltage with respect to the grid; a first RF drive configured to apply an RF signal between the cathode and grid at the fundamental and third harmonic RF frequencies; and a second RF drive configured to apply an RF drive signal to the accelerating/bunching cavities. Electrons are emitted by the cathode and travel through the grid to the accelerating/bunching cavities for input into an RF linac.Type: GrantFiled: May 17, 2011Date of Patent: October 22, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Phillip A.

Patent number: 8351476Abstract: A system and methods for the quasi-remote compression and focusing of a moderate-intensity laser pulse to form a much higher intensity beam that can be directed at a target and used as a probe beam or used in a probe beam converter to generate other forms of electromagnetic radiation or energetic particles. A system for the quasi-remote propagation of high-intensity laser beams in accordance with the present invention comprises a main platform on which a first, “seed” laser pulse is generated, stretched, and amplified, and a remote platform, located at a distance from the main platform, which is configured to receive the amplified and stretched pulse and convert it into the high-intensity laser beam. The high-intensity laser beam in turn can then be converted into one or more probe beams directed at a target object.Type: GrantFiled: June 21, 2012Date of Patent: January 8, 2013Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Richard F. Hubbard, Antonio C. Ting, Joseph R. Peñano, Daniel F. Gordon, Phillip A. Sprangle, Bahman Hafizi, Arie Zigler

Patent number: 7260023Abstract: A method for generating an acoustic source in a liquid includes transmitting an optical pulse through the liquid so the optical pulse reaches ILIB through pulse compression and ionizes a liquid volume. The pulse compression is achieved through at least one of a) group velocity dispersion induced longitudinal compression of a frequency chirped optical pulse and b) transverse self focusing via a nonlinear optical Kerr effect. The acoustic source can be generated at a controllable remote location many meters from the optical source. The optical source can be a laser or other suitable optical device.Type: GrantFiled: November 2, 2005Date of Patent: August 21, 2007Assignee: United Statesof America as Represented by the Secretary of the NavyInventors: Theodore G Jones, Antonio C Ting, Phillip A Sprangle, Leonard Dale Bibee, Joseph R Penano
