Wavelength tunable Q-switched fiber lasers have important applications in the fields of communication, medicine, ranging finding and laser processing. A continuously tunable Q-switched all-fiber Er-doped laser based on a 45°-tilted fiber grating and tunable bandpass filter is demonstrated. Under the pump power of 655 mW, stable Q-switched pulses with central wavelength of 1548 nm, average output power of 4.45 mW, repetition rate of 105 kHz, and signal to noise ratio (SNR) of 39.89 dB are obtained. Furthermore, the Q-switched optical spectrum can be continuously tuned from 1512 nm to 1552 nm by simply rotating the tunable bandpass filter with 655 mW pump power. As far as we know, this is the widest tunable range of tunable Q-switched fiber Lasers based on nonlinear polarization rotation effect and tunable bandpass filter.
