Claim:
1. A system for separating pump light and collected light in a laser pumped light source comprising: a pump source configured to generate pumping illumination including at least a first wavelength; a gas containment element for containing a volume of gas; a collector configured to focus the pumping illumination from the pumping source into the volume of gas to generate a plasma within the volume of gas, wherein the plasma emits broadband radiation including at least a second wavelength; and one or more illumination separation prism elements positioned between a reflective surface of the collector and the pump source and arranged to spatially separate the pumping illumination including the first wavelength and the emitted broadband radiation including at least a second wavelength emitted from the plasma, wherein the one or more separation prism elements are positioned such that the pumping illumination including the first wavelength enters the one or more illumination separation prism elements at a first face and broadband radiation including the at least the second wavelength enters the one or more illumination separation prism elements at a second face different from the first face.
