haven't you just described how to make a laser?
- rowanG077 6y agoNo a laser is coherent. It has almost the same intensity in it's entire path. If you know the approximate distance you can accurately focus a normal beam of Light into that area. Killing the bug but much safer.

- danielheath 6y agoThis would protect people standing behind the bug, but if the system mistakenly identified an eye as a bug you would still be delivering a burning quantity of energy focussed on the eye.
