    High-intensity beam cuts and welds high-heat conductive metals.
    FIGURE 1. Chirally coupled core (3C) optical fiber mode propagation (a), a 33 μm core-diameter fiber image (b), simulated modal loss vs. wavelength for the two lowest fiber modes (c), and mode beat analysis for well-aligned and offset 33 μm fibers are shown. A spectral beating analysis that looks at the magnitude of fiber mode beating as a function of misalignment of a launched signal shows effectively no beat, indicating high-purity single-mode operation.

    SOLID-STATE LASERS: VBG upper-state pumping benefits DPSS lasers

    Michael Atchley
    March 1, 2013
    Properly optimized volume Bragg grating (VBG)-based upper-state laser diode pumping leads to performance and power improvements for diode-pumped solid-state (DPSS) lasers.
