The current state of single frequency fiber laser technology based on different saturable absorbers (SA) is reviewed. The proposed and experimental fiber lasers used ytterbium-doped fiber (YDF) as the gain medium and the mode selection is done by Sagnac interferometer loop mirror filter (LMF) incorporated SA. In this paper, we review the experiment principle and process of SF fiber lasers utilizing different function materials as the SA, including the fabrication, features of the two-dimensional (2-D) materials (graphene and molybdenum disulfide film) SA. The SA is like a narrowband filter to ensure the longitudinal mode operation. Finally, we systematically analysis and compare the experimental results based on different SA. © 2017 SPIE.

A high-stability wavelength-Tunable single-frequency (SF) ytterbium-doped all-fiber compound ring laser has been demonstrated experimentally. The compound ring cavity is composed of a fiber optical tunable filter, a high-finesse ring filter, and a loop mirror filter. Three segments of ytterbium-doped fibers are employed as the gain medium or saturable absorber, respectively. The SF operation is observed to be stable during 1 h without mode hopping. The SF fiber laser achieves a wide-band tunability from 1030 to 1090 nm with maximum output slope efficiency of 7.95%. The power instability over 2 h gives standard deviation value of 1.34%. The average linewidth is 8.8 kHz and the relaxation oscillation frequency is at 62 kHz. © 2009-2012 IEEE.

We report on an ultrahigh repetition rate harmonic noise-like Er/Yb-doped double-cladding fiber laser that can operate through the nonlinear polarization evolution mechanism. High-order harmonic noise-like pulses (NLPs) with a repetition rate as high as 115 GHz have been generated in fiber lasers. At the cavity dispersion of net anomalous, the noise-like pulse with the full width at half maximum of 15 nm was generated at a central wavelength of 1560 nm, with an output power of 628 mW at the pump power of 8 W. These results could be useful for understanding the generation of higher power and higher repetition rate NLPs in passively mode-locked fiber lasers. © 2017 Astro Ltd.

We experimentally demonstrate a wavelength-tunable passively mode-locked Yb-doped all-normal-dispersion fiber laser by exploiting a high-birefringence Sagnac fiber loop as a flexible filter. The wavelength of pulses is controlled by properly rotating the polarization controllers in a Sagnac loop. The spectrum of output pulses could be shifted by up to 15 nm at a repetition rate of 18 MHz. Output power of more than 43 mW at pulse durations below 11.4 ps is achieved at the central wavelength of 1035 nm. The pulse temporal frequency and output power change slightly over the tunable range. © 2016 Astro Ltd.
