Journal ArticleDOI
Generation of sub-nanosecond pulse in dual-wavelength praseodymium fluoride fibre laser
Harith Ahmad,M.H.M. Ahmed,M.Z. Samion,A.A. Kamely,Mohammad Faizal Ismail,Sulaiman Wadi Harun,K. Thambiratnam +6 more
Journal ArticleDOI
Tunable S-band output based on Raman shift in dispersion shifted fiber
TL;DR: In this article, a tunable short-wavelength band Raman fiber laser using a dispersion shifted fiber as the nonlinear medium is proposed and demonstrated, which provides an alternative to the common method of using depressed-cladding, erbium-doped fibers as the gain medium in S-band fiber lasers.
Journal ArticleDOI
Ultrafast mode-locked dual-wavelength thulium-doped fiber laser using a Mach-Zehnder interferometric filter
TL;DR: In this article, a dual-wavelength mode-locked laser using a tunable Mach-Zehnder filter (TMZF) and a single-wall carbon nanotube (SWCNT) based saturable absorber (SA) is proposed and demonstrated.
Journal ArticleDOI
Dual-Wavelength Holmium-Doped Fiber Laser Pumped by Thulium–Ytterbium Co-Doped Fiber Laser
Anas Abdul Latiff,Anas Abdul Latiff,Anirban Dhar,Sulaiman Wadi Harun,I M Babar,Shyamal Das,Mukul Chandra Paul,Harith Ahmad +7 more
TL;DR: In this paper, the authors presented an all-fiber dual-wavelength holmium-doped fiber laser operating in 2μm region using a newly developed Holmium doped fiber (HDF) as a gain medium.
Journal ArticleDOI
Gain clamped double-pass L-band EDFA with incorporation of FBG at the input end of the optical amplifier
Sulaiman Wadi Harun,Harith Ahmad +1 more
TL;DR: In this paper, a gain-clamping technique in two-stage double-pass L-band EDFA is demonstrated using a single fiber Bragg grating (FBG), and two types of FBGs, broadband and narrowband, have been used in the gainclamped system.
