Abstract
Using wavelength beam combination, we report greater than 100 W out of a 100 μm core, 0.2 numerical aperture fiber. We emphasize that this is reliable CW power from an optical system that does not suffer from distortion due to heating in gold-coated, polymer-based diffraction gratings. We show that using high-brightness bars with single-mode emitters, the wavelength beam combination technique is capable of achieving high power out of a 50 μm core, 0.2 numerical aperture fiber with good coupling efficiency.
