Large-mode-area single-mode-output Neodymium-doped silicate glass all-solid photonic crystal fiber

Abstract

We have demonstrated a 45μm core diameter Neodymium-doped all-solid silicate glass photonic crystal fiber laser with a single mode laser output. The structure parameters and modes information of the fiber are both demonstrated by theoretical calculations using Finite Difference Time Domain (FDTD) method and experimental measurements. Maximum 0.8 W output power limited by launched pump power has been generated in 1064 nm with laser beam quality factor M 2 1.18.
