    I’ll have to see if I can find where I read this to cite the source.

    The National Ignition Facility is researching using insanely huge lasers to start a nuclear fusion reaction. They are currently the most powerful laser in the world.
    Want to know what the second most powerful laser in the world is? The reflection of the NIF laser.

      Meanwhile, China is now making very cheap welding and cutting lasers for consumers, the reflections off these can blind in a millisecond. My lab has multiple redundant safety protocols and strictly monitored training, expensive goggles, key lock interfaces, panic stop buttons and we are at 1/100th the power of these laser welders getting pointed at shiny metal.
