@GabrieleVierti I misread that as "Detective Laser Cutter". I would name the character Douglas Ohms, descendant of the great robot detective Surelock Ohms.
Loss of lenses may transform Detective Ohms from a coherent bright beam into a dangerous loose cannon! It's now up to his algorithmic associate, Wattson to solve the case!
@Almo But I think they mean that lasers don't diverge - they stay sharply targeted in a small hit area even over long distances, rather than spreading / blurring.
I mean, you can. My laser cutter does for instance. The beam is somewhat bright at its initial width, but use a lens to focus it to a point and now you can melt and burn and cut with it.
Right, if the laser beam is wide. But that is not a function of the laser; it is something you do afterward. So "laser-like focus" still makes no sense since they don't focus ordinarily.
