Question:
Is there a lazer powerfull enough to hit against an object, bounce back, and move the object?

Replies:
Not directly, unless the object is very very light, because light carries very little momentum. However, a powerful laser heating an object can vaporize the surface rapidly enough that the expanding vapor creates sufficient pressure to push the object. This is the way laser-driven fusion works.
