This paper aims at optimizing the absorption of the pump beam by core location in double-clad fiber lasers for circular and D-shaped fibers using practical data. The results indicate that, in a fiber with circular geometry, the absorption of the pump is increased by increasing the distance of the core from the center. However, in a D-shaped fiber, the variation of pump absorption has an optimum point. Considering these variations in the D-shaped fiber, a new optimum location for the core is obtained in which the pump absorption is increased from 91% to 97%.
Keywords: double clad fiber laser, core location, ray tracing method
