Is the problem that the light can have a physical impact, so it does not meet the light standards that have been implemented?
Yeah, pretty much. Refer to this
If it comes out as a laser cutter, it should cut, not flatly impact. Even if some stuff does apply, having light do non-light stuff like this is an instant disqualification (unless there's an explicit reason for it like Legend having such fine control that he can both bend his lasers and have them travel at the speed of light by overt statement)
There is a little bit of leeway since I've heard it's theoretically possible for a laser to have force, but that would require it to be in excess of City Block level (and that's a little iffy anyhow)
