A laser illuminating apparatus that illuminates a linear or strip-shaped area (S) of sheet material (B) with high radiant power contains a diode laser (2) whose output is followed by two mutually orthogonally oriented rod lenses (4, 6) whose focal length is small in comparison to their distance. Between the two rod lenses (4, 6) a laser light beam fan (L2) is formed. Said fan is focused by the second rod lens (6) on a narrow linear area (S). Behind said area the laser beams diverge at a large angle (α) so that the power density decreases accordingly rapidly. If the light falls on the retina of an observer's eye, the laser light is not focused pointwise but only linearly, which excludes injury to the eye due to the accordingly low power density.
