We report an investigation of the dependence on transition dipole moment isolated line intensities in degenerate four-wave mixing A2Σ+ (υ′ = 0) ← X2Π (υ″ band for NO. For spectrally integrated we found that was well described by a power law μx, where μ is one-photon moment. As result saturation, exponent x depends laser intensity. The observations are reasonable agreement with simple two-level model [ Opt. Lett.294 ( 1978);Opt. Lett.3, 205 1978)], which predicts limiting dependences μ8 and μ3 low high intensities, respectively. At intermediate consistent observed rapid decrease increasing intensity, followed plateau extending to intensities.
