Abstract

A tunable passively Q-switched for S+/S band thulium-fluoride fiber (TFF) laser using single-walled carbon nanotubes as a saturable absorber is proposed and demonstrated. The tunability of the proposed laser covers a wavelength region of 1450.0–1512.0 nm, with a range of 62.0 nm. Stable Q-switched operation can be obtained at a pump power of 115.7–229.9 mW at 1492.0 nm. The resulting pulses have a measured repetition rate and pulse width of 12.0–36.4 kHz and 6.2–3.6 μs, respectively. The maximum pulse energy that was achieved in this experiment is 122.8 nJ. To the author’s knowledge, this is the first reported tunable passively Q-switched TFF laser that covers the S+/S region that has been demonstrated.
