Abstract :
We studied squeezing in the difference of the field amplitude in degenerate six wave interaction process, which is a higher-order squeezing effect. It is shown that for uncorrelated modes the normal squeezing in the difference-frequency field directly depends on the difference squeezing of input field modes. It is established that the amplitude-squared squeezing of the fundamental feeds directly into the normal squeezing of the signal mode. Detection of difference and amplitude-squared squeezing in this process is also studied. It is found that squeezing is greater in stimulated process than in spontaneous interaction.
