摘要： A laser produced plasma device comprises a shutter assembly for mitigating the contaminating effects of debris generated by the plasma. In one embodiment, the shutter assembly includes a rotatable shutter having at least one aperture that provides a line-of-sight between a radiation source and an exit of the device during a first period of rotation of the shutter, and obstructs the line-of-sight between the radiation source and the exit during a second period of rotation. The shutter assembly in this embodiment also includes a motor configured to rotate the shutter to permit passage of the X-rays through the at least one aperture during the first period of rotation, and to thereafter rotate the shutter to obstruct passage of the debris through the at least one aperture during the second period of rotation.

摘要： A system and method is disclosed for generation of a nanoplasma and/or nanofluorescence. The system includes an emissions source of soft x-rays. The emissions source can include a laser system as an energy source and target material that acts as a radiation source when illuminated by the laser system. The system further includes focusing optics particularly suited for manipulation of wavelengths associated with x-rays. The focusing optics can focus the x-rays onto a desired target so that a nanoplasma or nanofluorescent spot can be formed to have a diameter of less than 200 nm. Radiation from the nanoplasma or nanofluorescent spot can be examined, for example using a spectrometer, in order to perform a highly-selective material analysis of the desired target. Other applications include using the nanoplasma for nanoablation and/or nanodeposition processes.

摘要： A sample analysis system comprises a laser unit and a spectrometer unit. The laser unit emits a first laser pulse and a second laser pulse towards the sample with a pulse separation time of between about 1 microsecond to 20 microseconds. The laser unit includes an oscillator unit which is configured to generate the first laser pulse and the second laser pulse. A pre-amplifier unit is configured to receive the first laser pulse and the second laser pulse and increase the energy levels of each pulse prior to the pulses being emitted from the laser unit. The spectrometer unit captures emissions generated by the sample after the sample is stuck by the first and second laser pulses and identifies the elemental constituents of the sample using the emissions.

摘要： An uncomplicated, compact and environmentally-immune sensor for the degreef articulation of finger joints in a remote underwater vehicle uses a length of an optical fiber connected to each finger joint. As the joint is rotated, the bending of the optical fiber changes the attenuation of light through the fibers and a detector monitoring this change provides a signal that is correlated to the degree of articulation.

摘要： A method and apparatus for laser cutting a target material is disclosed. The method includes the steps of generating laser pulses from a laser system and applying the laser pulses to the target material so that the laser pulses cut through the material. The laser pulses have an approximately ellipse shaped spot, have a temporal pulse width shorter than about 100 nanoseconds, and have an energy density from about 2 to about 20 times the ablation threshold energy of the target material. The laser pulses are applied to the material such that the major axis of the ellipse shaped spot moves parallel to the cutting direction. The spot has a leading edge and a trailing edge on the major axis, and the energy density of each laser pulse increases from zero to a maximum along the leading edge and decreases back to zero along the trailing edge. The apparatus is a laser system for cutting a target material that includes: a seed laser system for producing a first pulse laser beam; a laser amplifier for amplifying the first pulse laser beam to produce an amplified pulse laser beam; a harmonic generation system for converting the amplified pulse laser beam into a second pulse laser beam having a shorter wavelength; a focussing system for focussing the second pulse laser beam to an approximately ellipse shaped third pulse laser beam; and a motion control system for moving a target material contacted by the third pulse laser beam.

摘要： A efficient point source x-ray target tape assemble. A tape is wrapped helically around a rotating drum a little more than one complete turn so as to create an overlap section where a section of the tape is positioned parallel and adjacent to a separate section of the tape. The tape advances slowly across the outside surface of the drum at a speed which is a small fraction of the tangential surface speed of said drum. In a preferred embodiment a pulsed laser beam is focused on the tape at a fixed spot in space through which the tape moves in order to create x-rays from plasma generated by very high intensity ablation of the tape material. The combination of the drum rotation and the tape advancement across the surface of the drum permits substantially full utilization of the tape material for generation of x-rays.

摘要： Disclosed herein are systems and methods for advancing tape/ribbon through a targeting area where laser ablation of the tape occurs in laser produced plasma equipment. Disclosed systems include a first positioning surface perpendicular to further positioning devices, where all of the positioning components work to precisely position the advancing tape in the point source area. After the first positioning device, the remaining positioning surfaces are parallel and provide positioning forces on the tape along a single horizontal axis, but in alternately opposing directions. Such forces assist to precisely position the tape in the desired target location, and to control the rate of advancement of the tape by imparting friction on the tape in alternating, opposing directions. A steady drive roller serves to pull the tape through the system, and works in conjunction with the friction imparted by the positioning surfaces to advance the tape at a substantially constant velocity.

摘要： An optical interference filter has narrow linewidth and wide acceptance ae and includes a hemisphere coated to provide a narrow bandpass filter at a desired wavelength at normal incidence while other wavelengths at normal incidence are absorbed or reflected. A photodetector placed at the center of the hemisphere detects the desired wavelength only. Other wavelengths that are shorter than the wavelength of the filter are transmitted through the filter to be absorbed by a black absorbing surface around the photodetector. Thus, only the frequency of interest at normal incidence provides a representative signal at the detector.
