Abstract
An optical system is arranged to deliver electromagnetic radiation in first and second different wavelengths to tissue to be treated therewith. The optical system forms the different-wavelength radiations into beams of different sizes and combines the beams on a common optical path. The different-wavelength radiations on the common optical path are projected by the optical system onto the tissue to be treated to form overlapping treatment spots of different sizes. In one example, the treatment spots are concentric and the size of the treatment spots and the ratio of the treatment-spot sizes can be selectively varied.
