Abstract
Dual-wavelength neodymium-doped fiber laser at 1.08 mu m based on bismuth-doped fiber in a ring cavity has been experimentally demonstrated. Using bismuth-doped fiber as a spectral filter introduces intensity-dependent gain to alleviate mode competition caused by homogeneous gain broadening in neodymium-doped fiber. A pure sinusoidal continuous wave with repetition rate of 9.1 MHz was generated at the output. At room temperature, the consistency in output intensity and the wavelength proves the steadiness of the proposed fiber laser. The system is simple, compact and in all-fiber configuration.
