A laser printer and an illumination system for the laser printer records onto light sensitive medial. The laser printer and illumination system includes laser diode arrays, array illumination optics and cross-array illumination optics. The cross-array illumination optics combine light beams from the laser diode arrays so as to illuminate a spatial light modulator and confine incident light within a cross-array width of the modulator.
