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 mW.The output pulses have a repetition rate and pulse width range of 30.1-40.0 kHz and 9.0-3.2 μs,respectively,with a maximum pulse energy of 28.9 nJ.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.
