Simple, low-cost and stable passive Q-switched thulium-doped fibre lasers (TDFLs) operating at 1892.4 and 1910.8 nm are demonstrated using 802 and 1552 nm pumping schemes, respectively, in conjunction with a multi-walled carbon nanotubes (MWCNTs) saturable absorber (SA). The MWCNTs composite is prep...
