4kW CO2, Jesus xD. I don't know if that is a lot, but sure sounds like it ^^

I'm happy I even got to work with some CO2 lasers around the 100W mark at a rapid prototyping workshop for a few years. I loved working with those, even if it was just on wood and acrylic (and they constantly needed recalibration and tuning).

Now I just sit at a computer all the time... I honestly miss that even just slightly more hands-on work ^^

    4kw is sort of a standard power output, although one place I worked at had a 7kw laser with a huge table, I think 20 feet by 40 feet.

    That said, 4,000 watts of laser beam is not a plaything. I got burns from reflections off aluminum sheet, but my favorite was the guy trying to navigate a forklift arond the worst laid out shop I ever saw. He hit the resonator cabinet and knocked the first mirror and waveguide off while the laser was running, and a spot got burned in the side of a panel truck.
