| 20120183008 | Surface Catalyst Infra Red Laser - An energy converter reacts hydrocarbons and air on a catalyst configuration to produce a population inversion. A photovoltaic system may extract the radiating energy, and a laser system may extract a significant fraction of the reaction energy in the form of coherent radiation. The flooding of the catalyst adsorption sites with fuel and the choice of catalyst predisposes the adsorbing oxygen molecules to create mono-atomic oxygen hot-atoms, which deposit the considerable energy of oxygen adsorption directly into a reaction channel of adjacent, adsorbed and simple fuel radicals, thereby producing simple, energetic product molecules, concentrating the energy in one or a few modes, and strongly favoring inverted populations. A solid state method to stimulate precursor chemisorbed specie dissociation accelerates the reaction rates, providing a method to greatly intensify pulsed power output, increase efficiency, and to facilitate nano-scale and micro-scale thermal energy heat rejection processes. | 07-19-2012 |

| 20080267243 | Composite material with proximal gain medium - An apparatus and related methods are described, the apparatus comprising a composite material layer configured to exhibit at least one of a negative effective permittivity and a negative effective permeability for radiation of at least one wavelength propagating therethrough. The apparatus further comprises a layer of gain material proximal to the composite material layer, the layer of gain material providing amplification for the propagating radiation. The layer of gain material is disposed within a laser cavity and pumped to a lasing condition for the laser cavity, the layer of gain material thereby providing gain-clamped amplification for the propagating radiation. | 10-30-2008 |
| 20080291963 | Fiber-based mid-infrared generation laser for laser ultrasound inspection - Embodiments of the present invention relate to a laser system and method for the optical generation of ultrasound at a remote target. This involves generating a pump laser beam with a diode-pumped fiber laser. The diode pumped fiber laser is fiber-coupled with an optical fiber, either passive or diode pumped, to a generation laser head. The generation laser head generates a generation laser beam from the pump laser beam and directs the generation laser beam to the surface of the remote target. The interaction between generation laser beam and the surface of the remote target results in ultrasonic displacements at the remote target. These ultrasonic displacements may be sampled in order to assess and inspect the remote target. | 11-27-2008 |
| 20090274189 | SCALABLE THERMALLY EFFICIENT PUMP DIODE SYSTEMS - Scalable, thermally efficient pump diode systems. These systems may include an arrangement of pump diodes and thermally conductive spacers mounted within a single indentation in a substrate or substrate clamps, so as to provide enhanced heat removal from the system. These systems also may include a plurality of such pump diode assemblies mounted, in a symmetric or partially symmetric arrangement, around a lasing medium in a diode pumped laser system, to improve heat removal and/or excitation of the medium. | 11-05-2009 |
| 20130089119 | LASER COMPRISING A LASER MEDIUM - A laser having a standing wave resonator including a first resonator section, which has at least a first end mirror and a second resonator section, which has at least a second end mirror. At least one of the optical elements of the first resonator section is embodied in focusing fashion. Accordingly, the beam axes of the laser beam which arrives upon respective tiltings of at least one of the optical elements in the second resonator section have at least one crossing point, which lies in the pump region of the laser medium or is at a distance from the pump region which amounts to less than the Rayleigh length. The radius (w) of the laser beam is less than five times the radius (w) of the laser beam in the pump region of the laser medium. | 04-11-2013 |
