Novel Processes in Laser Micro-fabrication and Micro-joining

By: Kazuyoshi Itoh, YasuyukiOzeki Department of Material and Life Science, Osaka University Focused ultrafast laser pulses can cause a variety of the structural modifications including void, damage, refractive index (RI) change, and crack, depending on materials and irradiation conditions such as pulse energy, pulse width and numerical aperture (NA) of the focusing lens. Among these modifications, […]
