Abstract
A frequency conversion system comprises first and second gain sources providing first and second frequency radiation outputs where the second gain source receives as input the output of the first gain source and, further, the second gain source comprises a Raman or Brillouin gain fiber for wave shifting a portion of the radiation of the first frequency output into second frequency radiation output to provided a combined output of first and second frequencies. Powers are gain enhanced by the addition of a rare earth amplifier or oscillator, or a Raman/Brillouin amplifier or oscillator between the high power source and the NFM device. Further, polarization conversion using Raman or Brillouin wavelength shifting is provided to optimize frequency conversion efficiency in the NFM device.
Claims14
A frequency conversion system comprising:
- a first gain source for providing a first frequency radiation output;
- a second gain source for receiving as input the first frequency output from said first gain source, said second gain source, comprising an optical fiber selected from the group consisting of a Raman gain fiber and a Brillouin gain fiber, for wave shifting a portion of the radiation of said first frequency output into a second frequency radiation output;
- and
- a nonlinear frequency mixing device coupled to receive said first and second combined first and second frequency outputs as an input from said second gain source to produce a third frequency radiation output from said nonlinear frequency mixing device.
