We report a passively Q-switched fiber laser operating at 1900 nm region using the newly developed Thulium Bismuth co-doped lithium-alumino-germano-silicate fiber (TBF) as a gain medium in conjunction with a multiwall carbon nanotubes (MWCNTs) based saturable absorber (SA). The TBF and MWCNTs are fa...
