A system and method for generating a two-dimensional optical or laser beam, line, or pattern includes a diffractive optical element (DOE) for changing or modifying an intensity distribution of an input optical or laser beam passing through the DOE. A focal lens receives the changed or modified optical or laser beam exiting the DOE and focuses the changed or modified optical or laser beam. A bifocal relay optics receives the focused optical or laser beam exiting the focal lens and magnifies, changes or adjusts at least one length or dimension or a shape of the focused optical or laser beam. Finally, an imaging optics receives, converges and outputs the magnified, changed or adjusted focused optical or laser beam exiting the bifocal relay optics as an output optical or laser beam.
