Claims22
A laser beam treatment apparatus comprising:
- a laser beam generating part generating and emitting a plurality of laser beams of different colors;
- and
- a projecting part condensing the plurality of laser beams and projecting the laser beams onto a treatment object region,
- wherein said plurality of laser beams include a first laser beam at a first wavelength, a second laser beam at a second wavelength different from said first wavelength, and a third laser beam at a third wavelength different from said first and second wavelengths,
- said projecting part emitting said first laser beam at a constant output reference level, and emitting said second and third laser beams so that output levels of said second and third laser beams vary oppositely with respect to said constant reference output level.
