Spectral Characteristic Analysis on Yb3+ Doping Double-Clad Photonic Crystal Fiber

Article Preview

Abstract:

The photonic crystal fiber was applied in high-power laser gain medium, because of its flexible and optical controllability and special structure, which can overcome the design flaws of common optical fibers effectively. This paper studied the Yb3+ doping double-clad photonic crystal fiber. Through the theoretical analysis and numerical simulation, it optimized the structure design, drew the high doping concentration and double-clad fiber samples, analyzed the absorption and fluorescence spectra of fiber core material, and tested the optical fiber spectrum features, which can improve the performance of high power fiber laser.
