Publication number: 20220173568Abstract: The system and method of using an ultra-short pulse mid and long wave infrared laser. The system is seeded with a 2 ?m laser source having a pulse duration in the femtosecond range. The beam is stretched, to increase the pulse duration, and the beam is amplified, to increase an energy level of the laser beam. Both mid wave IR and long wave IR seed beams are first generated, and then amplified via one or more optical parametric chirped-pulse amplification stages. A compressor may be used to compress one or more of the output beams to achieve high peak power and controllable pulse duration in the output beams. The output beams may then be used to create atmospheric or material effects at km range.Type: ApplicationFiled: December 2, 2020Publication date: June 2, 2022Applicant: BAE SYSTEMS Information and Electronic Systems Integration Inc.Inventors: Peter A. Budni, Alan R. Enman, Yannick C. Morel

Patent number: 9859178Abstract: A microwave module is described. The microwave module includes a base bracket, a window plate and a lid. The base bracket is configured to contain a photoconductive switch, a radio-frequency transformer and dielectric oil. The window plate, which is transparent to optical light, covers a first portion of the base bracket in which the photoconductive switch is located. The window plate is sealed to the base bracket. The lid, which includes a cutout to allow the radio-frequency transformer to pass through the lid, covers a second portion of the base bracket in which the radio-frequency transformer is located. The window plate is sealed to the base bracket, and the lid is sealed to the window plate, the base bracket and the radio-frequency transformer to contain the dielectric oil within the microwave module.Type: GrantFiled: October 7, 2015Date of Patent: January 2, 2018Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Yannick C. Morel, Sheila J. Konecke, Santos Nazario-Camacho, Clint J. Novotny, Keith K. Sturcken

Patent number: 9306371Abstract: A Multi-Cycle Digital High Power Microwave (MCD-HPM) source includes a microwave transmission line (MTL) to which a plurality electrically charged thin film transmission lines (TFTL's) are connected by switches. The switches are activated in sequence to generate a square wave at a microwave output frequency. The activation signal is controlled by a free space time delay, which can vary the timing and/or routing of the activation signal by modifying at least one free space element, thereby adjusting the switch activation timing and varying the output frequency. In embodiments, the switches are photo-conducting switches, the activation signal is a laser beam, and the switch timing is varied by reorienting and/or repositioning mirrors and/or other elements in the free space time delay. The elements can be manually adjusted, or mounted on motorized stages and automatically controlled. Optical amplifiers can be included to compensate for losses in the time delay elements.Type: GrantFiled: April 20, 2012Date of Patent: April 5, 2016Assignee: BAE Systems Information and Electronic Systems Intergration Inc.Inventors: Yannick C Morel, John E McGeehan, Clint J Novotny, Simon Y London

Patent number: 9140864Abstract: Disclosed is a method of coupling light into a power semiconductor device having a semiconductor structure with two or more layers. The power semiconductor device has multiple cells of functionally identical units linked by multiple interconnects. In each device unit, a patterned electrode layer is disposed on the surface of the semiconductor structure. The method includes illuminating the power semiconductor device by directing a light from a light source through the patterned electrode layer to form an enhanced light coupling with the semiconductor structure. The patterned electrode layer is configured to have a micron scaled grid pattern having multiple metal grids and aperture openings that is based on a distributed resistance model having two characteristic current decay lengths.Type: GrantFiled: May 9, 2012Date of Patent: September 22, 2015Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Yeuan-Ming Sheu, Yannick C.
