Patent number: 10879665Abstract: The present disclosure relates to systems and methods for reducing thermal effects in double-clad clad optical fiber amplifying systems via control of the pump absorption. One optical fiber amplifying system for reducing thermal effects includes one or more first optical pump sources, each configured to output radiation of a pump wavelength, a bridge optical fiber, having an input configured to receive the radiation of the pump wavelength output by the one or more first optical pump sources and an output, and an active optical fiber that has a first end substantially directly coupled to the output of the bridge optical fiber and a second end. The active optical fiber is configured to amplify radiation of the first active wavelength when pumped with radiation of the pump wavelength.Type: GrantFiled: February 15, 2018Date of Patent: December 29, 2020Assignee: NufernInventors: Clemence Jollivet, Kevin Farley, Kanishka Tankala, John Edgecumbe

Patent number: 10630040Abstract: The present disclosure relates more to mode mixing optical fibers useful, for example in providing optical fiber laser outputs having a desired beam product parameter and beam profile. In one aspect, the disclosure provides a mode mixing optical fiber that includes a core having a refractive index profile; and a cladding disposed about the core. The core of the mode mixing optical fiber supports at least two (e.g., at least five) guided modes at the wavelength. The mode mixing optical fiber is configured to substantially distribute optical radiation having the wavelength propagating therein (e.g., input at its input end or generated or amplified within the core) among a plurality of the guided modes (e.g., to distribute a substantial fraction of the optical radiation having the wavelength propagating therein from its lower-order guided modes to its higher-order guided modes).Type: GrantFiled: February 6, 2017Date of Patent: April 21, 2020Assignee: NufernInventors: Clemence Jollivet, Kevin Farley, Jaroslaw Abramczyk, Michael Conroy, Kanishka Tankala, Peyman Ahmadi, Eric Lim
