Abstract: A scanning laser apparatus for alternately processing two workstations includes a 2D laser beam scanner and a roof reflector. The roof reflector has two reflective surfaces located on the left and right sides, respectively, of the roof “ridge”. The laser beam scanner directs the laser beam to either one of the left and right reflective surfaces of the roof reflector. When the laser beam scanner directs the laser beam to the left (or right) reflective surface, the left (or right) reflective surface reflects the laser beam toward a workstation on the left (or right) side of the roof ridge. The roof reflector divides the field of view of the laser beam scanner between the workstations. While a workpiece is being removed from or mounted in the left workstation, another workpiece may undergo scanning laser processing in the right workstation, and vice versa, thereby facilitating high throughput.

Abstract: An apparatus for radial laser processing of a workpiece, located on a center axis, includes a laser beam scanner directing a laser beam along but offset from the center axis, and a bi-conical reflector system including first and second conical mirror surfaces surrounding the center axis. The first conical mirror surface faces away from the center axis to reflect the laser beam radially outwards therefrom, toward the second conical mirror surface. The second conical mirror surface faces the center axis to reflect the laser beam radially inwards toward the workpiece. The laser beam scanner azimuthally scans a location of incidence of the laser beam on the first conical mirror surface to scan an azimuthal angle of propagation of the laser beam from the second conical mirror surface toward the workpiece. The apparatus enables irradiation of the entire circumference of the workpiece without physically rotating the workpiece.
