Abstract
An optical device is described for generating a sharp illuminating line on an illuminating plane from a high-power laser beam. The sharp illuminating line includes long and short axes. The optical device comprises an anamorphic setup of imaging and homogenizing optical systems for the separate imaging and homogenizing of the laser beam in the directions of the long and short axes. For imaging and homogenizing the laser beam in the direction of the short axes, a slit is illuminated homogeneously and the slit is imaged on the illumination plane by reducing optics.
