摘要
A stable, passively Q-switched thulium fluoride fiber laser（TFFL） using a multi-walled carbon nanotube（MWCNT）-based saturable absorber（SA） for operation in the S-band region is proposed and demonstrated.The proposed TFFL has a central lasing wavelength of 1486.4 nm and an input power range of 87.1–126.6 m W.The output pulses have a repetition rate and pulse width range of 30.1–40.0 k Hz and 9.0–3.2 μs, respectively,with a maximum pulse energy of 28.9 n J. This is the first time, to the author’s knowledge, of the successful demonstration of a passively Q-switched S-band TFFL using an MWCNT-based SA.
