@wa7iut@nyrath Note that a 10s-of-watt laser with a 1 arcsecond beam, such as DSOC on Psyche, is strictly a communications system and very much not a "long range laser weapon".
Even the 5 kW laser used for uplink is only ~4.5 Suns of brightness when it comes out of the telescope at Table Mountain (although one should not park something that absorbs near-IR in the beam for very long).
