ABSTRACT:
An optical print head for recording on a medium includes a plurality of lasers having laser emissions within a desired wavelength range, an optical fiber adapted to receive combined light from the plurality of lasers at a first end and to emit combined output light at a second end, and includes a hybrid optical element optically coupled to the second end of the optical fiber and adapted to focus the combined output light within the desired wavelength range on the medium.
