Abstract:
The concept of amplitude-cubed squeezing is introduced and shown to be a nonclassical effect. It is shown that such squeezing may be generated in some nonlinear systems, such as second and third harmonic generations. In particular, the normal squeezing of the third harmonic depends directly upon the amplitude-cubed squeezing of the incident light in the fundamental mode.
