1. A multi-station laser ablation apparatus for simultaneously micro-machining a plurality of target objects, wherein the system comprises:

  • a laser device for selectively generating a plurality of input laser beam pulses along a central axis;

    a laser scanning mechanism including a rotating member disposed to rotate around the central axis, and an optical system that is fixedly mounted on the rotating member and arranged such that the plurality of input laser beam pulses are redirected from the central axis to a circular scan path defined around the central axis, whereby output laser beam pulses are selectively produced on the circular scan path, anda plurality of stations circumferentially disposed around the central axis, each station including means for moving a corresponding one of the plurality of target objects in a corresponding radial direction relative to the central axis such that said corresponding target object intersects a corresponding portion of the circular scan path.
