These are dangerous lasers and there are restrictions in place governing their legal operation in the USA. For instance, before you can legally "fire" a laser this powerful into the sky, you must first obtain an FAA waiver (some observatories aim powerful lasers like this into the sky to help with their adaptive optics). Similarly, if you intend to use a laser like this in a public place, you're required to file documentation with the FDA. If you don't follow these rules and you get caught, your ass is grass.
So while the company is probably correct in that these lasers are legal (to possess), the actual use of these lasers may not be. One wonders if the company could be held partially responsible for any damages or injuries from the indiscriminate use of one of these.
