Abstract: A laser device is provided for the co-axial positioning of plural laser beams of same or different wavelengths along a single axis. At least two laser oscillators are provided, each producing a laser beam. A rotary reflector is positioned for intercepting at least one of the produced laser beams and directing the intercepted laser beam separately from, but along a single axis defined by another laser beam.
