Solid state system for frequency conversion using raman-active media and non-linear media

A solid state system for converting the frequency of a laser beam, said system comprising:

• a) a laser resonator;
• b) a lasing medium positioned inside said laser resonator for emitting said laser beam upon stimulation, such that said laser beam propagates within said laser resonator;
• c) a secondary resonator located inside said laser resonator, said secondary resonator comprising an incoupling means for admitting said laser beam into said secondary resonator;
• d) a solid Raman-active medium disposed inside said secondary resonator for shifting the frequency of said laser beam by a characteristic frequency of said solid Raman-active medium to generate a Raman beam;
• e) a solid non-linear medium disposed inside said secondary resonator for shifting the frequency of said Raman beam to generate an output beam;
• and
• f) a first output coupling means for extracting said output beam from said secondary resonator;
• and
• g) a second output coupling means for extracting said output beam from said laser resonator.
