Kth-power amplitude squeezing (KPAS) is introduced and examined in the nonlinear-harmonic-oscillator model and the Jaynes-Cummings model with an intensity coupling. We discover that, in these two cases, the long-time behavior of KPAS (k\ensuremath{\le}4) for the strong initial field periodically displays a collapse-revival-valley and squeezed collapse-revival phenomenon, respectively. For a nonclassical state, the relation between KPAS and ordinary squeezing, Hong-Mandel squeezing, and antibunching is investigated. The results show that KPAS is another intrinsic and independent nonclassical effect inequivalent to the last three.

We show that the amplitude Nth-power squeezing can be produced in kth-harmonic generation. The amplitude Nth-power squeezing of the fundamental can exist if the kth harmonic is originally in a coherent state which includes the vacuum. It is also shown that the normal squeezing of the kth harmonic depends on the amplitude kth-power squeezing of the fundamental.

We have studied the amplitude kth power squeezing in squeezed number states and derived the general formulas related to the squeezing effect. The squeezing propereies have been obtained for the cases of k=1,2,3 and 4 by means of numerical calculation, The results show that the AKPS has favourable applications in optical communication.
