Plasmonic nanoscale devices/structures have gained more attention from researchers due to their promising functions and/or applications. One important technical focus on this rapidly growing optical device technology is how precisely control and fabricate nanostructures for different or applications (i.e., patterning end points should locate at/near the interface while fabricating these plasmonic nanostructures), which needs a systematic methodology machining, patterning, fabrication when...
The angled and tapered antireflection transmission-enhanced fiber-optic tips were designed, fabricated, characterized based on nanoscale surface modification using the nano-precision focused ion beam (FIB). developed optical fiber showed combined functions of transmission enhancement for higher detection efficiency or signal-to-noise ratio because FIB-milled nanoholes into tip endfaces could act as air-filled nanopillars, changing light propagation direction, enhancing scattering effect,...
Assist gases, including combustion-supporting gas and shielding gas, can greatly affect laser drilling process drilled hole quality. In this study, oxygen argon were used for assisting pulsed of nickel-based superalloy plates. Influential mechanisms on processes discussed. Effects microhole entry, wall quality (defects, morphology, surface roughness), efficiency analyzed. It was shown that oxygen-assisted could achieve higher (threshold pulse number argon-assisted is relatively high)....
Ultrasound-assisted pulsed laser drilling is one recently-developing technique. In this study, nickel-based superalloy GH4037 sheets were drilled using the self-developed ultrasound-assisted Nd:YAG precision system, which incorporated self-designed ultrasonic vibration system and as integrated processing system. Effects of on microhole morphology wall quality analyzed through corresponding comparisons. Decrease degree for recast layer wave was also disclosed. It shown that axial might...
