| Abstrakt: | A theoretical study is made of the effect of a random medium upon the difference frequency wave produced by non-linear interaction. The difference-frequency mean square fluctuation level is shown to depend upon a series of coherence functions. An application of the theory to a simple but reasonably practical model establishes that the non-linear system in a random medium behaves virtually identically to a linear system operating in the same environment and at the same frequency in a number of practical cases. A simple method of experimentally verifying this result is suggested. |
