Abstract
The Optical Parametric Oscillator is a convenient device for downconverting a pump wave at a frequency of ωp to two frequencies at ωs and ωi. In this contribution, since we will present with multiple parametric interactions in series, we will call signal the field which is common to all interactions whatever its frequency. The quantum efficiency (ηq) is the ratio of the number of photons converted at <os to the initial number of pump photons. The energy conversion efficiency at 10s is related to the quantum one by the following relation:
