Abstract
A laser arrangement includes a laser array including a plurality of Vertical Cavity Surface Emitting lasers and an optical structure including a diffuser arranged to change a distribution of the laser light. The optical structure is configured to transform the laser light to transformed laser light such that an overlap of the emission cones of at least a group of the plurality of lasers is increased in field-of-view in comparison to perfectly collimated laser light diffused to a flat-top intensity profile in the field-of-view. The optical structure is arranged to redirect the laser light emitted at angles of the emission cone to the field-of-view so as to increase the overlap of the emitted laser light in the field-of-view. The optical structure is also configured to provide a slope angle α of an intensity profile along a direction of the field-of-view that is smaller than a divergence angle of the laser.
