Effects of Thermal Annealing on Femtosecond Laser Micromachined Glass Surfaces [PDF]
Micromachines, 2021 Femtosecond laser micromachining (FLM) of fused silica allows for the realization of three-dimensional embedded optical elements and microchannels with micrometric feature size. The performances of these components are strongly affected by the machined surface quality and residual roughness.
