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

open access: yesMicromachines, 2020
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).
