Laser tanks are impractical. What if the enemy wears mirrored shades? That laser goes right back and kills you instead. You don't want your 100 million dollar tank to be taken out by a pair of Ray-Bans.
The Army has officially deployed a pair of high-energy lasers overseas to blast incoming enemy drones out of the sky, the service recently confirmed, marking a major milestone for the U.S. military's ongoing development of futuristic directed-energy weapons.
The 20-kilowatt Palletized High Energy Laser, or P-HEL, "is currently deployed to support the Army's mission" in an undisclosed location abroad, a spokesman for the service's Rapid Capabilities and Critical Technologies Office, which manages its directed-energy portfolio, told Military.com.
I think the bigger concern is enemy UAVs wearing shades.
The moment those mirrors stop being perfectly shiny they begin thermal collapse. Which is the real reason mirrors exposed to the atmosphere can't be used as targeting optics.
The US military has in the past used some large vehicle mounted beam weapons that make your skin burn like all hell, such as the Active Denial System, and I wonder if those could be deflected as well or if they're the part of the spectrum that needs more sophisticated shielding?
That would work if the earth wasn't flat. As it is, you need to transport the artillery below their position and shoot them from there. Like Ender shooting through the ice clouds.
...the color of a blaster bolt (character-scale or starship scale) is determined by the quality of the gas used in it - higher quality gives you green, lower quality gives you red. The Rebellion didn't have access to the highest quality gas, and had to make do with the lower quality ammunition.
Huh, I guess I wondered but never looked it up until now.
I mean, that's how it was retconned, but it was originally just so viewers could tell if it was the good guys or bad guys shooting. Just like there were only supposed to be blue (good guys) and red (bad guys) lightsabers. As the Star Wars universe and lore expanded, things got retconned and added/changed/removed, and it's still happening with the new stuff that comes out. Isn't world-shaping neat?
I may risk being too credible here, but a $80 drone is a lot more expendable than a $40m laser tank. The drone can be considered a consumable. Hell, mark the drones down as ammo.
Mirrors melt and break when hit with a laser of more than "pretty lights power".
This dude built a 2kW one with optics: https://www.youtube.com/watch?v=xNmbvaUzC8Q

EDIT: I know where I am, that video is too good not to share though. Vote away.
Nah. This doesn't count because that guy is clearly from the future when you can buy a 1K laser at the corner store. In 2024, they are a little bit harder to come by.
This was a real concept for the anti-ICMB 747. The idea was to loiter it outside air defense range and then send drones in as reflectors to target the lasers much closer to the threat.
