Abstract

Abstract

It is reported that the mode-locking starting is achieved more quicker by injecting pulses noise into figure-of-eight Yb3+-doped fiber laser. A detailed investigation about this phenomenon is presented in this paper. Analyzing the process of the mode-locking in the cavity, we discover the noise in the cavity does affect the mode-locking starting process of the fiber laser. During the experiment, when the pump power is 214.75 mW, the figure-of-eight Yb3+doped fiber laser without injecting noise can generate locked-pulse in 30～50 seconds; while the pulses with duration of 30 ns, 10 kHz repetition frequency, and 0.2 mW is injected into the cavity, the fiber laser can generate locked-pulse in 1~2 seconds.
