Abstract
Single-frequency distributed Bragg reflector fiber laser at 915 nm was demonstrated by using a 2.5-cm long Nd3+-doped phosphate fiber as the gain medium. An output power of 13.5 mW was obtained at an absorbed pump power of 240 mW. Our experimental results show that Nd3+-doped phosphate glass fiber is more efficient than Nd3+-doped silica glass fiber for single-frequency laser operation in the 900 nm wavelength range.
