Hi Viktor,
Speaking about the 20W pulsed fiber laser: which wavelength? I did try using 1065nm 20W Q-switched fiberlaser to no availability. It would not cut tape or paper at all. At best, I could burn paper (very slowly).
Same question about laser diodes: which wavelength?
Also, if you happen to have any photos of the results, I would be very grateful if you can post them.
This is true. The hope is to use camera perception and only cut where it still needs it; not guaranteed to work, of course.What's another problem with "undefined" materials -- if you cut through, theres's noting, what will stop the beam from burning the space inside too!!
