A multiple stage laser system that produces coherent light in the ultraviolet range using phase conjugated Stimulated Raman Scattering and harmonic generation. The system uses a pump laser producing an input beam that is frequency shifted via phase conjugating Stimulated Raman Scattering. The Raman shifted beam is passed through a harmonic generation stage that produces the desired output beam by generating the required harmonic of the Raman shifted beam.
