| Abstract: | Self-Q-switched Er-doped fiber laser has been studied in this paper. Er-doped fiber is applied as gain medium, which is pumped by CW 980 nm LD. A fiber grating is used as the wavelength selector and cavity reflector. The stable self-Q-switched laser output is realized based on the nonlinearity of SM fiber—stimulated Brillouin scattering. The repetition rate about 64.5 MHz, and the full width at half maximum (FWHM) about 2.2 ns are obtained. |
