no, thats not a joke, and you are wrong, the most powerfull lasers on the world actually exceed 1petaWatt and are not used for military purpose at all. i regularly work on a 100terraWatt laser. dont forget, its not only about fluency, its also about intensity, a nuclear power plant delivers megaWatts,but over a year or so, standard high power lasers do that in femto seconds (10to the negative 15).
