Coherent combining of mid-infrared difference frequency generators
Abstract:
We report what is, to the best of our knowledge, the first experimental demonstration of coherent combining of two mid-infrared difference frequency generators by active phase control in the continuous-wave regime. Using the phase relation that is inherent to the nonlinear process, we are able to phase lock and combine the idler waves by the sole phase control of one of the pump waves. This control is done by an all-fiber electro-optic modulator. Combining is achieved with an excellent efficiency with a residual phase error of λ/28.
