Abstract :
We demonstrate an all-solid Nd 3+-doped silicate photonic crystal fiber with 13.1 W output power at 1061 nm and 64.5% slope efficiency. We also theoretically investigate and prove the effects of confinement loss and overlap fraction on a double-clad photonic crystal fiber laser. An innovative design is suggested to improve the laser beam quality.
