Micromachining of Invar Foils with GHz, MHz and kHz Femtosecond Burst Modes

Micromachining of Invar Foils with GHz, MHz and kHz Femtosecond Burst Modes

In this work, a burst mode laser is used for micromachining of 20 µm–250 µm thick Invar (Fe64/Ni36) foils. Holes were drilled by firing multiple pulses transversely onto the sample without moving the beam (percussion drilling). The utilized laser system generates a burst of a controllable number of...
