50kW class laser.
Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern — unclear if it’s a phased array (would be awesome) or just trained on the same target (source mentions they are “combined using a mirror” so probably the latter).
Sounds like maybe high power YAG?
It’s a matter of perspective and use — high density one place means you can have open space somewhere else, for a given amount of land.
I’d much prefer a few large dense housing complexes, surrounded by green space, than suburban sprawl.
