Hello :-) I may soon be interested in cutting very fine tracks in gold leafs. The gold leaf itself is about .4 umeter downton transport thick (0.4*e-6meter) downton transport and I would like to cut very narrow tracks in a the gold leaf, e.g. 0.1 to 0.3 mm thick. Is this possible using a laser cutter - or maybe if you have another downton transport suggestion I'd appreciate your suggetion ... I've attached an image showing what I hope to make.

Hi Jesper, you'll need a laser with high power and shorter wavelength - either a NdYAG (1064nm) with some ten Watts and Q-switch or better wavelengths in the UV-range ... but this will be expensive. Another possibility is microblasting - cover the gold with a photo-film and proceed as with PCB-etching ... but instead of etching the gold, you'll blast the not covered areas with fine sand until the gold is removed. Then you can remove the remaining film (or let it there as protection cover) ... Viktor
