Temperature-insensitive miniaturized fiber inline Fabry-Perot interferometer for highly sensitive refractive index measurement
TL;DR: The miniaturized fiber inline Fabry-Perot interferometer, with an open micro-notch cavity fabricated by one-step fs laser micromachining, is reported for highly sensitive refractive index measurement.
Journal ArticleDOI
Heat and mass transfer in gas metal arc welding. Part II: The metal
J. Hu,Hai-Lung Tsai +1 more
TL;DR: In this paper, a unified comprehensive model was developed to simulate the transport phenomena occurring during the gas metal arc welding process, where an interactive coupling between arc plasma; melting of the electrode; droplet formation, detachment, transfer, and impingement onto the workpiece; and weld pool dynamics all were considered.
Journal ArticleDOI
Improved Two-Temperature Model and Its Application in Ultrashort Laser Heating of Metal Films
Lan Jiang,Hai-Lung Tsai +1 more
TL;DR: In this paper, the authors extended the two-temperature model to high electron temperatures by using full-run quantum treatments to calculate the significantly varying properties, including the electron heat capacity, electron relaxation time, electron conductivity, reflectivity, and absorption coefficient.
Journal ArticleDOI
Miniaturized fiber inline Fabry-Perot interferometer fabricated with a femtosecond laser.
TL;DR: A miniaturized inline Fabry-Perot interferometer directly fabricated on a single-mode optical fiber with a femtosecond laser is reported, attractive for sensing applications in high-temperature harsh environments.
Journal ArticleDOI
Modeling of transport phenomena in hybrid laser-MIG keyhole welding
Jia Zhou,Hai-Lung Tsai +1 more
TL;DR: In this paper, the authors investigated the complicated transport phenomena in spot hybrid laser-MIG keyhole welding and found that weld pool dynamics, cooling rate, and final weld bead geometry are strongly affected by the impingement process of the droplets in hybrid laser MIG welding.
