A 3kW laser will not cut you in two, it will only give you severe burns.
Just a couple of weeks ago I finished making a cutting head that was installed on a laser cutter with a 4kW laser. It is quite common now to have 3 or 4kW lasers on laser cutting machines and there are quite a few of them in that power range in Australia.
