Color xerographic printer with multiple linear arrays of surface emitting lasers with dissimilar polarization states and dissimilar wavelengths

摘要

A color printer uses multiple linear arrays of surface emitting lasers of differing wavelengths and polarization states to simultaneously expose widely separated positions on the same or different photoreceptors. Each array is imaged by the same optical system to the photoreceptor. The multiple linear arrays can be closely spaced in a monolithic structure.
