Abstract: A laser-operated light source encompasses a chamber for accommodating a gaseous medium for generating a plasma, which emits radiation in response to the operation of the light source under the impact of the laser radiation. The light source encompasses a housing for accommodating the chamber. The invention provides for optical filter means, which are assigned to the housing and/or which are arranged downstream from the housing in the light path of emitted radiation. The optical filter means serve to spectrally filter the radiation emitted by the plasma in response to the operation of the light source.
