| 20090238220 | REDUCTION OF SURFACE HEATING EFFECTS IN NONLINEAR CRYSTALS FOR HIGH POWER FREQUENCY CONVERSION OF LASER LIGHT - A device for generating a high power frequency converted laser beam includes a nonlinear optical crystal having an entrance surface and a curved surface. The nonlinear optical crystal is configured to receive at least one laser beam at the entrance surface and provide a frequency converted beam through a frequency conversion process. The device also includes an optical coating coupled to the curved surface. The reflectance of the optical coating is greater than 50% at a wavelength of the frequency converted beam. Additionally, the far field divergence angle of the frequency converted beam increases after reflection off the curved surface. The device further includes a heat sink in thermal contact with the optical coating. | 09-24-2009 |
| 20090296199 | Laser amplifiers with high gain and small thermal aberrations - The present invention discloses a laser amplifier with high gain and low thermally induced optical aberrations on the amplified laser beam. The amplifier designs allow simple multipass configurations to optimally extract the gain and reduce thermally induced index of refraction aberrations, making it possible to obtain an amplified laser beam of high quality combined with very high overall gains comparable to those achievable with expensive regenerative amplifiers. The amplifier includes a thin active laser solid to create the population inversion and associated heat generation within the thin laser active solid possible for the desired gain value. The system includes a cooling device in thermal contact with the thin active laser solid to provide good heat transport and high reflectivity coatings at the wavelengths of the pump and laser wavelengths. The pump light sources are laser diodes tuned to the maximum absorption of the laser active material. The amplifier also includes an optical system to transport the pump light to the laser active solid in such a way as to further confine the absorption of light along the two orthogonal directions in the plane of the laser active solid in order to get high population inversion and consequently high gains possible. | 12-03-2009 |

| 20090158720 | Sliding Seat And Exhaust Gas Treatment Facility - The present invention relates to a sliding seat for mounting a thermally impacted pipe on a structural part so as to be axially movable, in particular in an exhaust gas system of a combustion engine, with a bearing material which is radially supported against pipe on the outside thereof and which is fixed on structural part via a retaining pipe fastened on structural part. | 06-25-2009 |
| 20100061898 | Exhaust Gas Retreatment Device - Provided is an exhaust gas retreatment device for an exhaust system of an internal combustion engine including a housing, in which an exhaust gas retreatment element and upstream thereof a silencer device are arranged, an inlet gas path leading from one housing inlet to an outlet of the exhaust gas retreatment element located in the interior of the housing, with an exhaust gas path following the inlet gas path which in the interior of the housing leads to the silencer device and/or through the silencer device as well as to a housing outlet. A cost-effective design can be achieved if the inlet gas path has a higher gas tightness than the exhaust gas path and/or if components of the exhaust gas retreatment device limiting the inlet gas path have a higher material quality than components of the exhaust gas retreatment device only limiting the exhaust gas path. | 03-11-2010 |

| 20100157280 | METHOD AND SYSTEM FOR ALIGNING A LINE SCAN CAMERA WITH A LIDAR SCANNER FOR REAL TIME DATA FUSION IN THREE DIMENSIONS - An apparatus and method for aligning a line scan camera with a Light Detection and Ranging (LiDAR) scanner for real-time data fusion in three dimensions is provided. Imaging data is captured at a computer processor simultaneously from the line scan camera and the laser scanner from target object providing scanning targets defined in an imaging plane perpendicular to focal axes of the line scan camera and the LiDAR scanner. X-axis and Y-axis pixel locations of a centroid of each of the targets from captured imaging data is extracted. LiDAR return intensity versus scan angle is determined and scan angle locations of intensity peaks which correspond to individual targets is determined. Two axis parallax correction parameters are determined by applying a least squares. The correction parameters are provided to post processing software to correct for alignment differences between the imaging camera and LiDAR scanner for real-time colorization for acquired LiDAR data. | 06-24-2010 |
