A fiber inline Mach-Zehnder interferometer (MZI) consisting of ultra-abrupt fiber tapers was fabricated through a new fusion-splicing method. By fusion-splicing, the taper diameter-length ratio is around 1:1, which is much greater than those (1:10) m

During new fiber sensor development experiments, an easy-to-fabricate simple sensing structure with a trench and partially ablated fiber core is fabricated by using an 800 nm 35 fs 1 kHz laser. It is demonstrated that the structure forms a Mach-Zehnd

In this study, experiments are carried out to demonstrate that in laser welding of a Zr-based (Zr52.5Ti5Al10Ni14Cu17.9) bulk metallic glass (BMG), pre-existing nuclei nucleus density has significant influence on its crystallization behavior. Based on

The application of bulk metallic glasses (BMGs) has been traditionally limited to parts with small dimensions and simple geometries, due to the requirement of fast cooling during the conventional process of casting. This research exemplifies a promis

Laser polishing is an innovative part-finishing process to reduce the surface roughness by melting a thin layer of material on the part surface. The polished surface quality is influenced by many factors including initial surface condition, propertie

Welding of dissimilar metals is challenging, particularly between crystalline metals and metallic glasses (MGs). In this study, Zr 65.7 Cu 15.6 Ni 11.7 Al 3.7 Ti 3.3 (wt%) MG structures were built on 304 stainless steel (SS) substrates by laser-foil-

Understanding the crystallization behavior of metallic glasses (MGs) during laser processing is important in additive manufacturing of MGs, which would overcome the limitation of section-thickness. Experiments were conducted to study the crystalline
