Different types of material (Silicon, ceramic, metals ) were machined using the same Teem Photonics HNG laser source and the same process.
All samples – including hard materials like tungsten or ceramics - could be processed with
moderate focusing conditions, demonstrating the intrinsic ablation capacity expected from such
high peak power pulses.
The majority of the grooves exhibit >150µm depth, and quasi-vertical walls (<3°), after 200
passes with no thorough process optimization.
There is no visible heat-affected-zone on the side of the groove, even for the 3 metals considered.
