Title:
METHOD OF CONVERTING LOW BEAM QUALITY TO HIGHER BEAM QUALITY
Document Type and Number:
Japanese Patent JP2022120095
Kind Code:
A
Abstract:
To provide low optical loss, a high numerical aperture (NA), and high optical gain for the fundamental propagating mode, or a linearly polarized (LP) 01 mode, in the UV and visible portions of the optical spectrum.SOLUTION: A multi-clad optical fiber design is described. The optical fiber design may contain dopants in order to simultaneously increase an optical gain in a core region and avoid additional losses during a fiber fabrication process. The optical fiber design may incorporate rare-earth dopants for efficient lasing. Additionally, modal characteristics of propagating modes in an optical core promote highly efficient nonlinear mixing, providing for a high beam quality (M2<1.5) output of emission light.SELECTED DRAWING: Figure 1
