    摘要: A method for amplifying optical signals and an optical fiber amplifier for accomplishing the same. An optical fiber is coupled to a source of pump light and a signal gain level is correlated to a dispersion value of the optical fiber that corresponds to a local minimum power level of a cross-talk signal generated by four wave mixing. Optical signals are transmitted through the optical fiber while admitting sufficient pump light into the fiber from the source to attain the selected Raman gain level.

    摘要: Disclosed are systems and methods for cutting one or more glass sheets. A system is provided comprising a first mirror having a first reflective surface and a second reflective surface that is spaced from and opposes the first reflective surface to define a cavity between the mirrors. An aperture can be defined in the first mirror. Furthermore, a laser beam can be provided that is configured to emit a beam through the aperture into the cavity. Beams reflected in the cavity, in one aspect, define a common focus point through which the glass sheet can be translated to cause the cutting of the glass sheets. A means for translating the glass sheet through the cavity is provided, in one aspect.

    摘要: A positioning method that calculates a lower accuracy positioning solution and applies an offset to the lower accuracy positioning solution to form a final positioning solution if a higher accuracy positioning solution is unavailable. The offset represents a difference between the lower accuracy positioning solution and the higher accuracy positioning solution at a point in time when the higher accuracy positioning solution was last available.

    摘要: The strain-managed optical waveguide assemblies of the present invention utilize a large-mode-area (LMA) optical fiber that is annealed in a first bending such that the fiber in that configuration has substantially no axial strain. A fiber support member is then used to support the annealed LMA optical fiber in a second bending configuration that forms within the LMA optical fiber an axial strain profile that reduces stimulated Brillouin scattering (SBS) as compared to the first bending configuration, and that also preferably causes the LMA optical fiber to operate in a single mode. The LMA optical fiber may have a double-clad configuration and include a doped core that serves as a gain medium. The strain-managed optical waveguide assembly can then be used to constitute a fiber amplifier that mitigates the SBS penalty associated with high-power fiber-based optical systems. The strain-managed waveguide assembly can also provide for thermal management in high-power applications, and can be used to control SBS by controlling the temperature profile along the length of the LMA optical fiber in a manner that mitigates SBS.
