    Feasibility of a low power etching laser setup

    Thanks for your answer KrowBar. Burning 30 um holes at 10 cm distance with additionally a small galvanometer mirror was my ideal setup. Based on your advice, I see that I have to be more flexible. I would also be happy with for example making 60-80 um holes at a distance down to 5 mm without...
