Titanium micromachining by femtosecond laser

, 2021
In the last two decades, there is a rapid increase in the femtosecond laser applications. Since this type of lasers produce ultrashort pulse durations, which means high peak powers can be obtained, they provide unique advantages. Also, nanoscale science requires structures, which are not possible to fabricate by conventional technologies.
