A color laser printing apparatus that incorporates the use of fiber optics and a flexible beam-combining device to combine two or more lasers having different wavelengths that correspond to the photosensitivities of the image-receiving media. Use of fiber optics on a flexible beam-combining device allows high flexibility in the placement of components associated with a color laser printing apparatus and making the system easier to align. Because the components of the system no longer require placement in close proximity to one another, certain aspects of the system can be made more compact and any adverse effects of heat generation of the components, such as the lasers, can be greatly reduced.

Using optical fiber multiplexer to combine light beams in a laser printer

An optical system for a laser printer. The optical system includes a diode laser for producing a laser beam at a predetermined wavelength for scanning across a photosensitive media. A single mode fiber is connected to the diode laser for transmitting the beam from the diode laser to an object plane.

Optical system for a laser printer

A mulitchannel optical waveguide page scanner has a diode laser and a primary optical channel waveguide. Light is coupled from the diode into the primary channel waveguide. Multiple secondary side channels each have a thin-film electro-optic waveguide modulator. A series of T-branch connectors distribute light from the primary channel to the secondary side channels. Each of the electro-optic waveguide modulators is addressable individually.
