摘要：
The possible mechanism for the generation of near three photon resonant third-harmonic in the low energy side of the 6(1)P1 state of Hg is described. It is shown that the existence of strong ac Stark effect, due to the presence of the additional resonance 6(1)P1 - 6(1)D2 via the fundamental photon, results in a spatially dependent phase mismatch, which can lead to nonzero radiation in the DELTA-k > 0 region. Additionally, the influence of the ac Stark effect as a saturation mechanism with increased incoming radiation power is described.
