Generation of q-switched thulium-doped fiber laser (tdfl) using differentsaturable absorbers
N. Mohd Sharif,N. Md. Yusoff,Mohd Azri Mohd Izhar,Fauzan Ahmad,Sulaiman Wadi Harun,Harith Ahmad +5 more
TL;DR: In this paper, a Q-switched Thulium-doped Fiber Laser (TDFL) operating at approximately 2 µm wavelength is successfully generated by using four different saturable absorbers (SAs) which are nitrogen-dope graphene in PVA (NG:PVA), nitrogen-depleted graphene in PE (NG):PEO, single-walled carbon nanotube in PE(SWCNT):PVA, and high pressure carbon monoxide carbon Nanotubes inPE(CNTHiPCO):PPA).

S. M Azooz,Ali Abdulhadi Jasim,Belal Ahmed Hamida,Harith Ahmad,Sulaiman Wadi Harun,A Halder,Mukul Chandra Paul,Shyamal Das,Mrinmay Pal,Shyamal Kumar Bhadra +9 more
TL;DR: An all-fiber dual-wavelength fiber laser operating at room temperature in the 1950 nm region is reported in this article, where a commercial Thulium-Ytterbium co-doped fiber (TDF) and homemade double-clad TDF as gain media in conjunction with a multimode interferometer (MMI) filter in a ring configuration are used.
