Claim 1:
2. The ophthalmic surgical laser system of claim 1, wherein the plurality of optical elements and the plurality of motors include:
a high frequency scanner configured to scan the pulsed laser beam back and forth along a fast scan line at a predefined frequency, the fast scan line being centered at a center position and oriented along an orientation;
a scan line rotator including a prism or a set of mirrors mounted on a rotating stage which is rotatable around an axis parallel to a propagation direction of the laser beam, and a first motor configured to drive the rotating stage, wherein the scan line rotator is disposed downstream of the high frequency scanner and is configured to rotate the orientation of the fast scan line;
an XY scan device including either (1) a focusing lens mounted on an XY scanning stage and a second and a third motor respectively configured to move the XY scanning stage in two orthogonal directions, or (2) two orthogonal scanning mirrors and a second and a third motor respectively configured to rotate the two scanning mirrors, wherein the XY scan device is disposed downstream of the high frequency scanner and is configured to move the center position of the fast scan line in two orthogonal directions perpendicular to the propagation direction of the laser beam; and
a Z scan device including a second lens and a fourth motor configured to move the second lens in the propagation direction of the laser beam, wherein the Z scan device is configured to move the center position of the fast scan line in the propagation direction of the laser beam.
