Patent ID: 7718921

Claim:
An apparatus for delivering laser energy from a source of laser energy to a target surface on a work piece, comprising: beam delivery optics having adjustable components arranged to receive the laser energy from an output of the source of laser energy and direct the laser energy along an optical path toward the target surface, the optical path including a variable segment between first and second components of the beam delivery optics having a variable length and variable direction through air and establishing an output beam line, wherein the first component is adjustable to define a direction of the variable segment and a second component is adjustable to define a length of the variable segment and an angle of incidence of the laser energy on the second component; and a controller, coupled to adjustable components of the beam delivery optics, to adjust the first component to change the direction of the variable segment and to adjust the second component to change the length of the variable segment and the an angle of incidence of the laser energy on the second component, in order to move the output beam line for the laser energy among target positions on the target surface.
