ABSTRACT:
Each laser of a semiconductor laser array of an optical system has its own lens mounted adjacent to it in the space between the laser array and the objective lens of the system. The purpose of the lenses is to change the angle of divergence of the light beams leaving the emitting surface of the laser array so that the light beams can be collected efficiently by the objective lens, thereby providing significant beam power at the light sensitive medium (optical disk, photoconductor, etc.) of the optical system. The focusing power of each lens is chosen to form virtual images behind the emitting surface with spacings approximately corresponding to the spacings of the light beams emitted by the laser array, but with the emitter image size substantially magnified.
