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.
Claims19
A laser device for co-axial positioning of plural laser beams along a single axis, which device comprises:
- at least two laser oscillators for producing a laser beam by each oscillator;
- rotary reflector means positioned for intercepting at least one of said produced laser beams and directing the intercepted laser beam separately from, but along a single axis defined by, the other laser beam;
- alignment means for aligning the respective laser beams of each said oscillator at an angle along paths which intersect at a region;
- said reflector means includes a reflecting member rotation means for rotating said reflecting member through said path intersection region;
- and
- said device includes control means for operating one of said oscillators to emit a pulse of said one laser beam only as said reflecting member rotates through said path intersection region so as to reflect said one beam pulse along said single axis and for operating another of said oscillators to emit a pulse of said other laser beam only when said reflecting member has rotated beyond said path intersection region so that said other beam pulse passes unobstructed along said single axis.
