Abstract
A device for processing light radiation, comprises: an optical input for receiving an input beam from an optical source and for propagating in the device an input radiation, an optical output for emitting an output beam having predetermined spatial parameters, an MPLC device, which is arranged between the optical input and the optical output, and which is configured to spatially separate, in a separation plane, the input radiation into useful radiation, in a target mode, which is propagated to the optical output and into an interference radiation. The processing device also comprises at least one blocking device for blocking the interference radiation, which blocking device is arranged in the separation plane so that it does not contribute to the output beam.
