Patent ID: 8724213

Claim:
High-power sum frequency generator system comprising: at least a first electromagnetic source such as a laser for generating a first fundamental field and a second fundamental field emitted along a propagation path, and a first nonlinear component and a second nonlinear component arranged in series along the propagation path, wherein: the first nonlinear component is adapted for generating a first sum frequency field from the first fundamental field and the second fundamental field, the first sum frequency field having a first polarization, the second nonlinear component is adapted for generating a second sum frequency field from the first and second incident fundamental fields, the second sum frequency field having a second polarization, the first and second sum frequency fields both propagating along the propagation path, and wherein the system has an output comprising the first sum frequency field and the second sum frequency field, and wherein a direction of the first polarization encloses an angle with a direction of the second polarization such that the two polarizations are non-parallel.
