Patent

CA 2401477

A description is given of a multibeam laser light source (10) with a number of preferably individual driveable laser light sources (12), which are arranged in an array, said light source (10) being distinguished by the fact that the spacing (130) of the light beam emitted by a first laser light source (12) from a light beam emitted by a second laser light source (12) can be varied by varying the pump energy distribution through the resonator of the first laser light source (12). A number of mutually insulated contacts (112) for current injection into each resonator is provided, so that a shift in the active region of the laser light source (12) at right angles to the emission direction is achieved by varying the driving of the contacts (112). The multibeam laser light source can be used with particular advantage in an imagesetting device for image carriers, in particular printing forms.
