A passively Q switched fiber laser near 2 m band was obtained based on semiconductor saturable absorber mirror and fiber grating. The central wavelength of the laser was 1958.2 nm. The pulse repetition rate of output signal increases with the rise of incident pump power, but the pulse width decreases. The pulse repetition rate was in the range of 20 kHz to 80 kHz and the pulse width was changed from 490 ns to 1 s. When the incident pump power was 1.3 W, the maximum output power of the Qswitched fiber laser was 91 mW, the pulse repetition rate was 80 kHz, the pulse width was 490 ns and the single pulse energy was 1.14 J.
