from what i read the laser is extremly dangerous even to those not even in the same room. if it gets reflected and hits someone in the eye even for 1/2 a second it can damage that person for life
I have a wicked laser spyder in arctic blue , that might work , you can see this laser cut the air and also burns paper and cuts through electrical tape!!
Laser would be a very dangerous tool for killing aiptasia and I don't see any manufacturer can legally sell those for aquarium use. I played with high-energy <1W lasers and without protective wear I wouldn't even touch it again. The reflected beam can damage your eye easily. Products like Aiptasia X or kalk paste in the needle work much better. True peppermint shrimp will help controling them, too.
