Disclosed is a laser having a laser diode coupled with a passive intra-cavity tapered waveguide.

Laser diode chip with waveguide

A laser imaging system for direct imaging with high optical power density a series of pixels forming an image on a media surface, The laser imaging system includes a laser light source, wherein the laser light source emits a laser beam representative of the image on the media surface. An optical path is defined between the laser light source and the media surface. A scanner is provided having a mirrored surface positioned along the optical path. An optical assembly is positioned along the optical path for shaping and focusing the laser beam at the media surface, including an F-Theta lens assembly positioned along the optical path between the scanner and the media surface. The F-Theta lens assembly includes a spheric lens, an aspheric lens and a toric lens, providing an increase in optical power density at the media surface.
