Death Star-like lasers become a practical reality

No, the invention isn’t going to be used for destroying rebellious planets. The military could certainly stand to benefit, though. Super-powerful lasers could quickly destroy drones and missiles that normally require a sustained laser attack to take down. There are some more peaceful purposes, too: for a start, spacecraft could use extra-powerful lasers to annihilate oncoming space junk. And when existing single-laser technology is frequently limited by overheating worries, it’s likely that there are many other potential uses that just haven’t been feasible until now.
