英文摘要:
This paper reports, for the first time to our best knowledge, a nearly diffraction-limited output in a Yb3+/Al3-/F- codoped double cladding silica fiber with a 50 mu m core diameter and 0.02 core NA. The core glass with a diameter >6 mm was fabricated through solgel process combined with high temperature sintering. Laser performances of this fiber at different bend diameters were studied. The mean M-2 < 1.1 in this 50 mu m core diameter fiber was achieved at a bend diameter of 0.35 m. The core glass with the refractive index nearly equal to pure silica glass is suitable for the fiber design, such as large-mode-area photonic crystal fiber. (C) 2016 Optical Society of America
