The effect of semiconductor saturable absorber mirror (SESAM) on continuous-wave multi-wavelength fiber ring-cavity laser with semiconductor optical amplifier (SOA) is experimentally demonstrated. The evolutionary process of multi-wavelength oscillation and the decrease of oscillating mode number caused by an SESAM are discussed. It’s found that the free oscillating mode number of the multi-wavelength fiber ring-cavity laser with SOA can be upto three, and the lasing wavelengths are 1573.8 nm, 1578.09 nm and 1582.37 nm, respectively. When a SESAM is inserted in the fiber ring-cavity, it narrows the amplified spontaneous emission (ASE) spectrum of the SOA, and the oscillating mode number of the multi-wavelength fiber ring-cavity lasers with SOA decreases to two, a stable dual-wavelength lasing at 1560.91 nm and 1564.12 nm is obtained.

This study reports a Q-switching-based, 2058-nm holmium (Ho) fiber laser incorporating a saturable absorber (SA) based on graphene oxide (GO). The SA was prepared with a side-polished fiber, while GO particles were deposited onto the fiber-polished surface to realize an all-fiber SA. A continuous-wave thulium-doped all-fiber laser, which was configured with a master-oscillator power-amplifier (MOPA) structure, was constructed as a pumping source. By inserting the fabricated SA into an all-fiber ring resonator based on 1-m length of Ho-doped fiber, Q-switched pulses could readily be obtained at a wavelength of 2058 nm. The pulse width was observed to vary from 2.01 to 1.56 μs as the pump power was adjusted from ~759 to 1072 mW, while the repetition rate was tunable from 45.56 to 56.12 kHz. The maximum values of average optical power and pulse energy were measured as ~11.61 mW and 207.05 nJ, respectively, at a ~1072 mW pump power.
