I've got a funny question I've sort of wondered about for around a decade now...



Is there some way of splitting a beam from a laser tag gun, or diverging it like a shotgun blast in order to gain an unfair advantage? Like with a lens or splitter of some sort?



I imagine the lasers they use in those guns would have to be really weak, since you're handing them to kids and telling them to point them at each other, but I also remember the targets being really sensitive, there was one kid who would reflect his beam off sparkles on one of the walls, in order to shoot around a particular corner...



I also contemplated bringing my own laser pointer to use as a second gun, but I was a naive kid and wasn't thinking of the modulation they use to determine who shot you... but would there be a way to put an optical sensor in there which would match the oscillation of the gun's beam and use that to drive a higher powered diode? (maybe not an optics question, but just throwing that out there).
