A laser assembly includes a laser and an articulated arm having a plurality of couplers arranged to receive a laser-beam from the laser. The assembly is mounted on a support structure, and is rotatable on the support structure in two axes perpendicular to each other. Six degrees of freedom of motion of the end of the articulated arm can be accomplished with one less coupler in the arm than would be necessary without rotation of the assembly on the support structure. |
