HIGH-POWER ELECTROMAGNETIC SUM FREQUENCY GENERATOR SYSTEM

摘要

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 forms a mutual angle with a direction of the second polarization such that the two polarizations are non- parallel.
