By controlling the transmitted resonant wavelength of a Fabry-Perot filter, stable single frequency laser output which is corresponding to one of the reflected wavelength of a five fiber Bragg grating wavelength division multiplexing (WDM) array as selective reflector was obtained with slope efficiency of -0.09. Experiment demonstrated that the lasing threshold is related to the grating's reflectivity and the gain of erbium-doped fiber at the working wavelength. Continuous tuning within the range of 1530 nm to 1575 nm could be achieved if the grating array was replaced by a board band reflective mirror.
