South Korea is beginning the mass production of a low-cost laser weapon that has successfully shot down small drones during testing, the country’s key arms agency said Thursday.
I think you’ve got it exactly right. Anything putting out kWs into the air is gonna light up the sky in its spectrum. Now, an ideal laser would be fully coherent with a perfectly planar wave and next to no spread. But even that would ionise the air in its beam, and with a very distinct fingerprint at that. I can’t really think of a way to make it truly invisible.
And you made a really good point that at this point you’re back to using cheap drones to expose and destroy million $ equipment
