摘要： A method for determining a position of a selected area of a sheet of material relative to a reference plane includes launching a first incident light beam at the selected area of the sheet of material such that the first incident light beam strikes the selected area at a first position and a first angle, thereby producing a first reflected light beam. A second incident light beam is launched at the selected area of the sheet of material such that the second incident light beam strikes the selected area at a second position and a second angle, thereby producing a second reflected light beam. The second position and second angle are different from the first position and first angle, respectively. The first reflected light beam and the second reflected light beam are intercepted at the reference plane. Information related to positions at which the reflected light beams were intercepted and angles at which the incident light beams were launched were received and correlated to the position of the selected area relative to the reference plane.

摘要： A method and apparatus using a gain medium in the form of a multiply clad gain fiber having an erbium-doped core. In some embodiments, aluminum and germanium are added to the silica core to make λ0 longer than the signal wavelength so the signal incurs normal dispersion. Optionally, a large-mode-area core amplifies primarily only one low-order mode because its NA is reduced by lowering the core's index of refraction (e.g., by adding fluorine) and/or by raising the index of the silica inner core (e.g., by adding germanium). Optionally, a thulium-doped region provides substantial loss at the first Raman-gain peak with respect to the signal wavelength but minimal loss at the signal or pump wavelength. Optionally, an inner cladding with a higher NA contains pump light within the outer boundaries of the cladding while allowing pump light to enter the core. In some embodiments, a triple cladding is provided.

摘要： Apparatus and method for spectral-beam combining light from a plurality of high-power fiber lasers that, in some embodiments, use two substantially identical diffraction gratings in a parallel, mutually compensating configuration to combine a plurality of separate parallel input beams each having a slightly different successively higher wavelength into a single output beam of high quality. In other embodiments, a single diffraction grating is used to combine a plurality of different wavelengths, wherein the input laser beams are obtained from very narrow linewidth sources to reduce chromatic dispersion. In some embodiments, diagnostics and adjustments of wavelengths and/or positions and angles are made dynamically in real time to maintain the combination of the plurality input beams into a single high-quality output beam.
