Abstract
In various embodiments, a laser head receives a laser output beam from a laser system or resonator without the use of a delivery optical fiber, and any asymmetry of the laser output beam may be maintained. The laser head may be physically rotatable to control orientation of the laser beam along a processing path on a workpiece.
Claims23
A laser system for directing a laser beam to a workpiece to be processed, the laser system comprising:
- a laser resonator comprising (i) a resonator housing, (ii) a plurality of beam emitters, each configured to emit one or more beams, disposed within the resonator housing, (iii) disposed within the resonator housing, a plurality of optical components for manipulating the beams from the beam emitters to form an output beam, and (iv) a resonator output for transmitting the output beam from the resonator housing;
- and
- a laser head positioned to receive the output beam from the laser resonator, the laser head comprising (i) a beam rotator configured to (a) receive the output beam and optically rotate the output beam by a rotation angle, and (b) be physically rotatable about an axis parallel to a propagation direction of the output beam, and (ii) focusing optics for focusing the output beam toward the workpiece.
