摘要： A system is described for testing aspheric optic elements by the interference of light beam components that are respectively directed to the element to be tested and to a reference element, which facilitates the testing. A reference element is deformable in a controlled manner to more closely match the element to be tested, to produce straighter and more even fringes.

摘要： A method passively locks and phases an array of fiber amplifiers in a fiber amplifier system that emits a beam, such as a laser beam. The method locks the fiber amplifiers so that the fiber amplifiers operate at same or similar frequencies. The method samples a small portion of the emitted beam in a far-field around a central lobe on an optical axis and then couples this portion of emitted beam back into the array of fiber amplifiers. The fiber amplifiers may be phased so that the emitted beam concentrates its energy around the central lobe in the far-field. Phasing may be achieved by using an aperture, for example, to restrict the portion of the emitted beam to be coupled back to a restricted region around the optical axis.

摘要： An apparatus and method for high power amplification in a multimode fiber amplifier. The apparatus includes a diffraction limited low power laser, a multimode fiber amplifier, and a lens. The multimode fiber amplifier is coupled to the low power laser to amplify the low power laser output. The multimode fiber amplifier has a length that is set to a phase-matching length at which the transverse modes of the multimode fiber amplifier are in phase. The lens is coupled to the multimode fiber amplifier and outputs a kilowatt (KW)-level, diffraction-limited output beam from the multimode fiber amplifier.

摘要： Means and methods are provided for controlling the geometry changes in a wafer or mask to permit patterns on the wafer to be matched with projected patterns from the mask. A sealed chamber is provided to receive the edges of the wafer or mask. Pressure is applied from a pressure source into the chamber against the edges of the wafer or mask uniformly in all directions to produce compressive strains until the desired wafer or mask geometry is obtained.
