Nd:YAG-Laser - anyone already used such a thing?

Hi folks,
has anyone any experience with Nd:YAG laser modules? I stumbled across a web article showing that such a laser can be used to evaporate copper from PCB raw material. That would just be cool! I certainly will put some research into it, but first let’s see if anyone already did :slight_smile:
Cheers
