Patent number: 11163111Abstract: A multi-clad optical fiber design is described in order to provide low optical loss, a high numerical aperture (NA), and high optical gain for the fundamental propagating mode, the linearly polarized (LP) 01 mode in the UV and visible portion of the optical spectrum. The optical fiber design may contain dopants in order to simultaneously increase the optical gain in the core region while avoiding additional losses during the fiber fabrication process. The optical fiber design may incorporate rare-earth dopants for efficient lasing. Additionally, the modal characteristics of the propagating modes in the optical core promote highly efficient nonlinear mixing, providing for a high beam quality (M2<1.5) output of the emitted light.Type: GrantFiled: April 27, 2020Date of Patent: November 2, 2021Assignee: Nuburu, Inc.Inventors: Mark S. Zediker, Robert A. Stegeman, James P. Tucker, Jean-Philippe Feve
