Abstract

In this study, we employ a segment of ytterbium-doped phosphate fiber, approximately 6 cm in length, as a saturable absorber to observe self-sweeping pulses, which represent a distinctive feature of the self-sweeping phenomenon. The resulting laser output exhibits a central wavelength of 1035.05 nm, accompanied by self-sweeping pulse intervals approximately 0.6 ms in duration. Radio frequency spectral analysis uncovers the presence of a 57.3 MHz signal. Our findings have the potential to expand the tuning capabilities of self-sweeping lasers and provide valuable insights into novel physical phenomena, thereby advancing the domain of fiber laser technology.
