Abstract
A high-power fiber laser exploits efficiency and wavelength-conversion of nonlinear wave mixing in a higher-order mode (HOM) fiber providing large effective area and higher-power operation than single-order mode (SMF) fiber. In a 'monomode' approach, mixing waves (pump(s), signal, idler) propagate in the same higher-order mode, and in an 'intermodal' approach different waves propagate in different modes. The monomode approach can provide high-power wavelength conversion generating output in a desired band where good dopants may be unavailable. The intermodal approach demonstrates coherent combining of outputs of multiple lasers to generate high-power output in a desired band.
