Transition Metal Dichalcogenides (WS2 and MoS2) Saturable Absorbers for Mode-Locked Erbium-Doped Fiber Lasers
Nur Ameelia Abdul Kadir,E.I. Ismail,Anas Abdul Latiff,Harith Ahmad,Hamzah Arof,Sulaiman Wadi Harun +5 more
TL;DR: In this paper, an ultrafast fiber laser based on transition metal dichalcogenide materials which are tungsten disulfide (WS2) and molybdenum disulfides (MoS2) as saturable absorber (SA) was demonstrated.
Journal ArticleDOI
155 nm-wideband and tunable q-switched fiber laser using an MXene Ti3C2TX coated microfiber based saturable absorber
Journal ArticleDOI
37.2 dB small-signal gain from Er/Yb Co-doped fiber amplifier with 20 mW pump power
Sulaiman Wadi Harun,Hairul Azhar Abdul-Rashid,S. Z. Muhd-Yassin,Mohd Kamil Abd-Rahman,Kanesh Kumar Jayapalan,Harith Ahmad +5 more
TL;DR: In this article, an efficient erbium andytterbium-doped fiber amplifier (EYDFA) was demonstrated by forward and backward pumping a 3 m erbiam/ytter bium co-oped fibers (EYDF) in single-and double-pass configurations using a 20mW pump.
Journal ArticleDOI
Generation of mode-locked erbium-doped fiber laser using MoSe2 as saturable absorber
TL;DR: In this article, a mode-locked generation of erbium-doped fiber laser (EDFL) with MoSe 2 thin film as saturable absorber is practically demonstrated.
Journal ArticleDOI
Fiber optic displacement sensor for imaging of tooth surface roughness
Husna Abdul Rahman,Husna Abdul Rahman,Hazli Rafis Abdul Rahim,Hazli Rafis Abdul Rahim,Harith Ahmad,Moh. Yasin,Retna Apsari,Sulaiman Wadi Harun +7 more
TL;DR: In this paper, a simple and inexpensive method using fiber optic displacement sensor is proposed for measurements of tooth surface roughness based on the intensity modulation technique, where a light beam was launched onto a tooth surface via a bundled fiber.
