Laser Beams Deflected Off of Nothing but Air for First Time Ever in Breakthrough Patent Pending Process - The Debrief::An international team of scientists report that they have successfully used acoustics to deflect laser beams in an engineering first.
I mean, that’s a 20GW laser, what about those handheld lasers? Would you still need 140db?
It would happen regardless of the power of the laser, but it would likely be undetectable at significantly lower power.
