摘要：

In this study, we demonstrate a wavelength-tunable passively mode-locked fiber laser based on a 45° tilted fiber grating and a tapered fiber using the nonlinear polarization rotation technique. Further, stable mode-locked pulses with a central wavelength of 1568.8 nm and output power of 2.31 mW can be obtained when the input pump power is increased to 454 mW. Accordingly, the 3-dB spectral bandwidth and pulse width are 4.5 nm and 1.3 ps, respectively. Subsequently, the central wavelength of the pulse can be continuously tuned from 1568.8 nm to 1560.24 nm using the tapered fiber as an adjustable attenuator to modulate the cavity loss. The demonstrated fiber laser can be used in several fields, including sensing, spectroscopy, and telecommunications. © 2019, Chinese Lasers Press. All right reserved.
