Abstract:
1. An apparatus for delivering laser energy from a source of laser energy, comprising: a relay imaging system which relays an image of an output of the source to a target image plane over an adjustable optical pathlength, the relay imaging system including input optics arranged to receive the laser energy from an output of the source of laser energy, a transmitting mirror mounted on a gimbal having an adjustable angle of incidence relative to the input optics, and a robot mounted optical assembly, the robot mounted optical assembly including a receiving mirror mounted on a gimbal having an adjustable angle of incidence relative to the transmitting mirror, and output optics directing the laser energy toward the target image plane; and a controller to configure the transmitting mirror, the robot mounted optical assembly and the receiving mirror to direct the laser energy through the robot mounted optical assembly to target positions on surface of a target work piece, and wherein the target image plane is within a range of distance before or after the target positions on the surface.
