Journal ArticleDOI
Fiber Optic Displacement Sensor Using Multimode Plastic Fiber Probe and Tooth Surface
TL;DR: In this paper, the performance of a fiber optic displacement sensor on a tooth surface is investigated by correlating the detector output with different probe configurations and various teeth samples with different surface reflectivity properties.
Journal ArticleDOI
Ultrahigh-Temperature Chirped Fiber Bragg Grating Through Thermal Activation
Xueguang Qiao,Yupeng Wang,Hangzhou Yang,Tuan Guo,Qiangzhou Rong,Ling Li,Dan Su,Kok-Sing Lim,Harith Ahmad +8 more
TL;DR: In this article, the feasibility of thermal regeneration of chirped fiber Bragg gratings inscribed in commercial singlemode fibers using a 248-nm excimer laser has been experimentally demonstrated.
Journal ArticleDOI
All-fiber multimode interferometer for the generation of a switchable multi-wavelength thulium-doped fiber laser.
TL;DR: The proposed multi-wavelength TDFL has potential to be employed in future thulium-doped fiber amplifier-based telecommunication infrastructure and also may be applicable in areas such as sensing and spectroscopy, largely associated with its 2 μm wavelength output.
Journal ArticleDOI
Compact Bi-EDF-Based Brillouin Erbium Fiber Laser Operating at the 1560-nm Region
TL;DR: In this paper, a single-frequency Brillouin erbium fiber laser (BEFL) was demonstrated operating at the 1560-nm region using a simple ring resonator with a very short piece of bismuth-based EDF.
Journal ArticleDOI
The generation of passive dual wavelengths Q-switched YDFL by MoSe2film
Harith Ahmad,F A A Rashid,Saaidal Razalli Azzuhri,M.A.M. Salim,R.A. Shaharuddin,M. A. Ismail,M.Z.A. Razak,M.Z.A. Razak +7 more
TL;DR: In this paper, a simple ytterbium doped fiber laser (YDFL) setup was used to generate Q-switching pulses by using a D-shaped polished fiber as a wavelength selective filter.
