Journal ArticleDOI
Dual-wavelength erbium-ytterbium co-doped fibre laser operating at 1064 and 1534 nm
Z. Jusoh,Sulaiman Wadi Harun,Nurul Shahrizan Shahabuddin,Harith Ahmad,Mukul Chandra Paul,Shyamal Das,Anirban Dhar,Mrinmay Pal +7 more
TL;DR: In this article, the authors demonstrate a simple erbium-ytterbium co-doped fiber laser with dual-wavelength output, which operates at 1064 and 1534 nm using a single gain medium.
Journal ArticleDOI
Soliton passively mode-locked pulses generation in thulium-holmium doped fiber laser (THDFL) with molybdenum oxide saturable absorber
TL;DR: In this article, the authors proposed and demonstrated stable passive mode-locking in a thulium-holmium doped fiber laser (THDFL) using molybdenum oxide (MoOx) deposited onto a tapered fiber as a saturable absorber (SA).
Journal ArticleDOI
Tunable and Low Noise Gain-Clamped Double-Pass L-Band Erbium-Doped Fiber Amplifier
TL;DR: In this paper, a low-noise and tunable gain-clamped L-band erbium-doped fiber amplifier is demonstrated using a Fabry-Perot laser in a double-pass system.
Journal ArticleDOI
Effects of an auxiliary pump on the performance of TDFA
Siamak Dawazdah Emami,Sulaiman Wadi Harun,F. Abd-Rahman,Hairul Azhar Abdul-Rashid,Harith Ahmad +4 more
TL;DR: In this paper, a dual-pumping scheme was used for ground state absorption to enhance the excited state absorption provided by the main pump of 1050 nm and thus to improve the gain and noise figure of the TDFA.
Journal ArticleDOI
Effect of CO 2 Laser Annealing on Stress Applying Parts Contributing Toward Birefringence Modification in Regenerated Grating in Polarization Maintaining Fiber
Man-Hong Lai,Kok-Sing Lim,Md. Rajibul Islam,Dinusha Serandi Gunawardena,Hangzhou Yang,Harith Ahmad +5 more
TL;DR: In this article, a CO 2 laser annealing technique was used to increase the birefringence of the regenerated grating in polarization maintaining fiber (RGPMF) by using an isothermal cooling process.
