Fabrication of a microresonator-fiber assembly maintaining a high-quality factor by CO2 laser welding

, 2015
We demonstrate fabrication of a microtoroid resonator of a high-quality (high-Q) factor using femtosecond laser three-dimensional (3D) micromachining. A fiber taper is reliably assembled to the microtoroid using CO2 laser welding.

Ytterbium fiber laser welding of Ti6Al4V alloy

Journal of Manufacturing Processes, 2015
Abstract In this work, full penetration welding of 2 mm thick Ti6Al4V plates in butt configuration was performed by adopting a high brightness Yb fiber laser. Neither groove preparation nor filler groove was used. The influence of different welding conditions on the bead morphology, metallurgy and mechanical properties was discussed in detail.
