Abstract:

Theory of intracavity parametric amplification at a low frequency pump has been developed in multilayer domain structure at the constant-intensity approximation. Analytical expression has been obtained for the optimum phase correlation between interacting waves. The numerous estimation of the expected conversion efficiency is presented for conditions of experiment. The author conducts the comparison between conversion efficiency at parametric amplification with a low frequency pump and the general case of frequency upconversion. It is shown that in the first case, by changing the entrance parameters of the signal wave and the wave at sum frequency, it is possible to affect considerably the dynamics of the nonlinear process and to achieve considerable transfer of pump energy to the wave of sum frequency, which heavily distinguishes this process from a traditional case of frequency up-conversion.

Keywords:

intracavity frequency conversion, constant-intensity approximation, the regular domain structure.
