ABSTRACT:
A dual resolution printer for printing images on an associated print medium includes: a light source providing a light beam and a focusing lens focusing the light beam and creating a converging light beam having at least one beam waist of at least one wavelength at a first beam waist location. The printer also includes an optical unit movable in and out of the converging light beam and having a corresponding first and second position, respectively. This optical unit, in the second position, reimages the beam waist of the converging light beam created by the focusing lens to a different size second beam waist, at a location substantially the same as the first beam waist location.
