AFAICT these things don't actually emit laser light, they use a high power laser to stimulate some sort of phosphorus-like material that then emits incoherent white light. The point is then that this secondary light source is very small (compared e.g. to LED with similar lumens), so the light can be much more easily focused by optics.
