Three Fiber Lasers Are Better Than One

Spectral beam combining produces three times the power in a near-diffraction-limited beam.

Breck Hitz

As scientists and engineers push fiber lasers to ever-higher output powers, they have encountered severe nonlinear effects that are a stubborn roadblock to further progress. The fundamental problem is the high power density propagating for long distances inside the fiber. Many efforts are under way to decrease the power density (usually by increasing the size of the mode propagating in the fiber) or to decrease the length of fiber required to make a laser (for example, by increasing the pump absorption). An alternative approach is to combine the beams of several moderate-power lasers to...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    power density
    In laser welding or heat treating, the instantaneous laser beam power per unit area. This parameter is key in determining the fusion zone profile (area of base metal melted) on a workpiece.
