Abstract
An apparatus and method for high power amplification in a multimode fiber amplifier. The apparatus includes a diffraction limited low power laser, a multimode fiber amplifier, and a lens. The multimode fiber amplifier is coupled to the low power laser to amplify the low power laser output. The multimode fiber amplifier has a length that is set to a phase-matching length at which the transverse modes of the multimode fiber amplifier are in phase. The lens is coupled to the multimode fiber amplifier and outputs a kilowatt (KW)-level, diffraction-limited output beam from the multimode fiber amplifier.
