Claim 16:
17. A writing module, comprising:
a plurality of integrated electronic modules each having an array having a plurality of individually controllable light sources each capable of controllably emitting a light beam directed onto an imaging surface adapted to carry particles of irradiation modifiable material;
each controllable light source comprises a cascade of at least two Vertical-Cavity Surface-Emitting Laser (VCSEL) light-emitting semiconductor junctions connected in series with one another and disposed to emit light along a common axis so as to direct a single beam onto a single spot on the imaging surface;
the writing module and the imaging surface being movable relative to one another, and the light beams of the plurality of light sources are spaced from one another in a direction transverse to the direction of movement of the imaging surface.
