Heh, that's cute. The issue with that is that locating UAV's that are, say 50 meters above the deck, more than 1km from your detector is essentially impossible. Without a VERY dense detection infrastructure, catching these things is not going to happen.
Furthermore even though these lasers are very cheap, by army norms, to fire, they're still 600$ or so for a single shot. So shooting down drones will be expensive. Far more expensive than the drones themselves.
Third. Defense against a laser is easy (a mirror, essentially, though you need to know the frequency to get an effective one). I must say that I don't know why you'd try to defend a drone. I'd try to hide it, since that's so easy.
And while a rules-based autopilot is easy to disrupt using jamming, a learned autopilot is essentially impossible to fool into crashing. Maybe you can divert it, I guess.
