Paper Abstract

An advanced design of an all-fiber passively mode-locked fiber ring laser is reported. By combining a fiber Bragg grating loop mirror with a segment of unpumped Er/Yb-codoped fiber as a saturable absorber, a stable continuous-wave mode-locking pulse with an even amplitude and a lowered noise background is obtained. The pulse width is narrower than 4 ns, with a repetition rate of 7.94 MHz. A high average output power of 319 mW and a slope efficiency of ~11.7% are achieved.
