Why do you want to use lasers? Do you think that maybe you just
point a laser at the object and it will magically become
balanced? Heck, no!

What a laser balancing system would need to do is mount the
object on a rigid frame with strain gauges in it to pick up the
vibrations from the imbalance. The object would likely be spun
on air bearings to eliminate vibrations from ball bearings.
A computer would analyze the vibration pattern and compute the
spot on the surface at the center of the excess weight, and
start blasting there every revolution of the object. As
material is ablated, the imbalance should decrease until the
centroid shifts, eventually the imbalance falls below some
threshold and the process is complete.

I really can't imagine setting up such a system in the home shop!
