TL;DR: In this paper, a Q-switched Brillouin-Raman fiber laser (BRFL) operating at 1563nm was demonstrated, using a 7.7 km dispersion compensating fiber (DCF) as nonlinear gain medium and graphene as a saturable absorber.

TL;DR: In this article, an MZI with a singlemode-multimode-singlemode multimode (SMSM) structure is developed for measuring acetone concentration in reverse osmosis (RO) water.

TL;DR: This paper demonstrated the nanosecond pulse laser operation at 1.55 and 2 μm wavelength regions using a newly develop chromium-doped fiber (CrDF) as a saturable absorber (SA) to convert efficiently continuous-wave laser operation to nanose Condensed Pulse Laser operation.

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).

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.
