More powerful than what? If StyroPyro can build handheld 200W+ LED laser device in his workshop [0], why wouldn't a sufficiently funded military be able to build an anti-drone laser with the same (or higher) power output?
Note that his laser burns through various reflective materials, including mirrors, copper, aluminium, and steel.
If a drone is 90% reflective it doesn't need a weapon besides your laser.. (If the star wars approach weren't a scam to enter an ever more expensive race as the side with more money than sense.)
