Patent number: 10687412Abstract: A photonic-crystal-fiber-delivered laser-triggered high-voltage gas switch can deliver a peak irradiance of greater than 5.1×1011 W/cm2 to the AK gap for a laser having a wavelength of 1064 nm. The switch is capable of operating at pressures up to 2200 psi; voltages across the gap of greater than 200 kV; operation at less than 70% self-break voltage; shot-to-shot jitter of less than 3 ns; AK gap distances of 3 mm or smaller; and triggering via a fiber-delivered laser pulse energy of as low as 500 ?J.Type: GrantFiled: September 9, 2019Date of Patent: June 16, 2020Assignees: National Technology & Engineering Solutions of Sandia, LLC, Colorado State University Research FoundationInventors: Sean Simpson, Owen Johns, Charles E. Rose, Azer Yalin, Ciprian Dumitrache

Publication number: 20110295140Abstract: A method and apparatus for analyzing trace levels of CO in human breath for the purpose of, among other things, assessing the severity of pulmonary diseases and monitoring the patient's response to a prescribed treatment. The apparatus measures in situ and in real time the CO concentration at sensitivity levels at least as low as parts per billion. A laser of the apparatus has a wavelength in mid-infrared (MIR) spectrum. The optical is constructed and arranged to perform cavity enhanced absorption spectroscopy (CEAS) the breath sample. The cavity includes highly reflective mirrors mounted to each side of the optical cavity to cause the light received from the laser to bounce back and forth within the optical cavity to increase effective path length of the light. A breath intake tube is connected to the optical cavity for collecting a sample of the patient's exhaled breath and transferring it to the optical cavity. A photo detector measures parameters of the light exiting the optical cavity.Type: ApplicationFiled: May 28, 2010Publication date: December 1, 2011Applicant: INTELLISCIENCE RESEARCH LLCInventors: Sohail H. Zaidi, Azer Yalin

Patent number: 7420662Abstract: A spark delivery system for generating a spark using a laser beam is provided, and includes a laser light source and a laser delivery assembly. The laser delivery assembly includes a hollow fiber and a launch assembly comprising launch focusing optics to input the laser beam in the hollow fiber. The laser delivery assembly further includes exit focusing optics that demagnify an exit beam of laser light from the hollow fiber, thereby increasing the intensity of the laser beam and creating a spark. Other embodiments use a fiber laser to generate a spark. Embodiments of the present invention may be used to create a spark in an engine. Yet other embodiments include collecting light from the spark or a flame resulting from the spark and conveying the light for diagnostics. Methods of using the spark delivery systems and diagnostic systems are provided.Type: GrantFiled: August 4, 2005Date of Patent: September 2, 2008Assignee: Colorado State University Research FoundationInventors: Azer Yalin, Bryan Willson, Morgan Defoort, Sachin Joshi, Adam Reynolds
