A laser is a collimated conherent beam, cutting would be done perpendicular. It would need a lot of particles to scatter off
I'm sure that if I tried to cut film on our laser (assuming I could put it in a dark room) it would fog it. There is a lot of light reflecting off of the substrate being cut and lots of flat panels to reflect it back.
