  • Patent number: 7787119
    Abstract: There is described a method for identifying at least one target in a substantially transparent medium. High-power, ultra-short laser pulses are transmitted into the medium. A diameter of the laser pulses is enlarged and the laser pulses having an enlarged beam diameter are focused using a focusing element so as to generate filaments substantially near a geometrical focal zone of the focusing element, whereby a spontaneous fluorescence signal (amplified through amplified spontaneous emission or not) is detected and analyzed to identify the target.

  • Publication number: 20090315297
    Abstract: Improved trailers (e.g., semi-trailers) are disclosed. The trailers may include a floor having a top surface and a bottom surface, where the top surface is adapted to transport a payload, and an elongated shell connected to the bottom surface of the floor, where the elongated shell defines a portion of a substantially closed torsion-resistant chamber of the trailer. The trailers may have a torsion resistance that is substantially higher than conventional trailers of similar size and/or load capacity. The trailers may weigh substantially less than conventional trailers of similar size and/or load capacity. The trailers may realize a bending resistance that is at least equivalent to the bending resistance of conventional trailers of similar size and/or load capacity.

  • Patent number: 7627006
    Abstract: A multi-wavelength laser source is provided including a pump laser unit, a gain section and an output. The pump laser unit generates an energy signal, which is applied to the gain section. The gain section includes a gain medium with having a superstructure grating forming a distributed Fabry-Perot-like structure. The superstructure grating causes a multi-wavelength laser signal to be generated when the energy signal is applied to the gain medium. The multi-wavelength laser signal is then released at the output.

  • Publication number: 20090274420
    Abstract: A system and method for permanently writing diffraction gratings in low phonon energy glass waveguides are shown. Ultrashort light pulses are generated and made to form two beams synchronously superimposed in the waveguide, therefore forming an interference pattern corresponding to the desired grating. The light pulses are focussed so that the light intensity in the waveguide exceeds a filamentation threshold. The exposure of the waveguide to these light pulses is controlled temporally and spatially in order to limit detrimental thermal effects induced by the high-intensity pulses in the glass medium of the waveguide.

  • Publication number: 20090236510
    Abstract: A radiation dosimetry apparatus and method use a scintillating optical fiber array for detecting dose levels. The scintillating optical fiber detectors generate optical energy in response to a predetermined type of radiation, and are coupled to collection optical fibers that transmit the optical energy to a photo-detector for conversion to an electrical signal. The detectors may be embedded in one or more modular, water-equivalent phantom slabs. A repeatable connector couples the collection fibers to the photo-detector, maintaining the fiber ends in a predetermined spatial relationship. The detector fibers may be distributed as desired in a three-dimensional detection space, and may be oriented with their longitudinal axes at different orientations relative to a transmission axis of an incident radiation beam. A calibration method uses two measurements in two spectral windows, one with irradiation of the scintillator at a known dose and one with only irradiation of the collection fiber.
