Abstract

An ultrafast high-repetition-rate mode-locked fiber laser based on a semiconductor saturable absorption mirror is reported in this paper. The repetition rate is as high as 1 GHz. A piece of single-mode EDF is used as the gain medium and a linear cavity is built. The central wavelength of the mode-locked fiber laser is 1561 nm, the spectral width is 10.10 nm, the pulse interval is 1ns, the RF signal-to-noise ratio is greater than 68 dB, and the pulse width is 247 fs. The experimental results show that the stable high repetition rate mode-locked pulse can be obtained through this simple and compact structure, and the application of the mode-locked laser in optical sub-sampling is verified.
