<p>An optical arrangement for light emitted by a linear laser emitting means and a linear laser emitting device comprise an optical distribution means arranged to distribute light emitted by at least one of the emitters to overlap, on a target plane, with light from at least one of the other emitters. The optical distribution means and optionally an optical redirection means are implemented as diffractive optical elements. For a material being processed that is located at least approximately in the target line, the invention allows to achieve a more even distribution of light or light energy over the material. <IMAGE></p> |
