Lasing characteristics of strongly pumped Yb-doped photonic crys...

A strongly pumped Yb-doped large-mode-area photonic crystal fiber (LMA-PCF) laser is analyzed. The lasing characteristics of an improved Fabry-Perot (F-P) cavity fiber laser using LMA-PCF are studied theoretically based on a rate equation model and the exact numerical solution of the rate equations is in excellent agreement with the experimental result.
