ABSTRACT:
A laser processing system is disclosed for providing a relatively small velocity of a laser beam at target location while at least one scanner scans at a relatively larger velocity. The system includes a laser source, a first scanning unit, a beam expander, a second scanning unit and focusing optics. The laser source is for providing a pulsed laser output having at least one beam with a beam dimension. The first scanning unit is for scanning the laser output in a first direction along a first axis at the target location. The beam expander is for receiving the laser output and for modifying a beam diameter of the laser output and providing a modified laser output. The second scanning unit is for scanning the modified laser output from the beam expander in a second direction along the first axis at the target location. The second direction is substantially opposite to the first direction along the first axis such that a net velocity of the modified laser output along the first axis at the target location may be made to be effectively zero during a laser pulse. The focusing optics is for focusing the modified laser output toward the target location.
