No. If you collide with it at 1m/h, then it doesn't bloody matter, that thing is almost in the same orbit as you, and it presents absolutely no threat to your spacecraft.
You care about micrometeoroids when they collide with you at any significant speed, at which point a laser can't do ANYTHING about it.
Unless we turn OP's idea on its head, and instead of trying to do something shield-like with passive lasers, we do an active system with just one laser, and some kind of tracking system that detects potential collisions, and then targets and eliminates those threats at a distance. Which is even more impossible from an energy usage perspective, and the detection and tracking would be insanely difficult.
