    Abstract: The superior performance of a saturable absorber (SA) based on randomly-oriented singlewalled carbon nanotubes (SWCNTs) operating in the spectral region of their first fundamental transition E11 over a graphene-SA containing several (n = 3) carbon layers and a commercial semiconductor SA (SESA) for passive Q-switching of bulk thulium solid-state lasers is demonstrated. Using SWCNT-SA in a compact diode-pumped Tm:KLuW laser, a maximum average output power of 1.36 W is achieved at 1932¿1944 nm corresponding to a slope efficiency of 41% and pulse characteristics of 48 ns/5.5 ¿J which are superior to that for graphene-SA (123 ns/3.1 ¿J) and SESA (61 ns/1.1 ¿J). SWCNT-SAs are promising for eyesafe miniature lasers at ~2 ¿m generating nanosecond pulses in the MHz repetition frequency range.
