Abstract
According to an embodiment of the disclosure, a system for producing a higher power laser beam is provided. The system includes an optical fiber having a length. The optical fiber is configured to receive inputs from multiple laser pumps and an input from a Stokes seed laser pump. The optical fiber has a core that is doped. The core, when viewed from a cross-section of the optical fiber, has a higher concentration of doping at a location near an axis of the optical fiber than a location further from the axis of the optical fiber. The optical fiber is also configured to convert pump power to Stokes power along the length of the optical fiber when subjected to a Stimulated Raman Scattering (SRS) process.
