Abstract: | Single-mode Nd3+-doped phosphate glass fiber with a core diameter of 8 μm was prepared. Laser properties pumped by an 800 nm laser diode were measured using a Fabry-Petor cavity. Laser emission centered at the wavelength of 1.053 μm,and a 1.053 μm CW laser with output power of 8.36 mW and slope efficiency of 30.6% were observed. |
