its actually not a laser at all... its more of a cellphone tower with directional output. my occupation is design and manufacturing of lasers used for joint pain and other medical applications. our company also produces the same thing thats on that truck in a smaller scale. and the radio frequency is chosen to counter act wifi and cell signal.
now if you want to know about a laser weapons, the us and china both shot down test satellites with ground lasers and we also have a orbiting satellite that has a laser for destroying intercontinental ballistic missiles, i think it puts out some ridiculous power out put.
most of those powerful lasers use a gas medium to lase rather than a semiconductor medium which is what laser pointers and lower out put projectors use now a days.
also a laser is not actually a thing its a acronym .
Light Amplification by Stimulated Emission of Radiation.
but me and my buddy have a constant debate weather or not its a action or a object.
