  • Wavelength Beam Combining for Power and Brightness …

    scale up in power with a diffraction-limited beam is an old one, with some pioneering work done at Lincoln Labo-ratory in the 1980s [1, 2]. Subsequent laser technology advances have allowed for practical implementations of those beam-combining concepts, and beam combining today is a well-accepted avenue for laser power scaling.
