Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A fiber laser, comprising: a higher-order-mode (HOM) fiber, the HOM fiber supporting a plurality of guided modes of propagation including higher-order modes, the HOM fiber having a predetermined mode-dependent dispersion characteristic defining a zero-dispersion wavelength for a first higher-order mode, the zero-dispersion wavelength defining a set of respective higher-order modes, wavelengths and phases of constituent optical signals of a predetermined patt…
