Is this something that can be solved from the ground (high powered lasers)? Or would we need mechanisms in space and up close to handle this kind of debris?
It might not be feasible for political reasons; I imagine most designs would also be excellent tools for disabling satellites, thus could start a space arms race. (Both China and the US have blown up satellites, but both were done with anti-satellite missiles; lasers might be more useful for starting a disastrous space war.)
However, to permanently disable them, it seems that more power is required, compared to adding velocity to small orbital debris.
If it could vaporize debris that came off of satellites or boosters or what have you, it could vaporize parts of satellites. Possibly at the rate of the metaphorical little bird that sharpens its beak on a mountain. :)
