In this paper, the higher power squeezing effects of generalized q-deformation superposition coherent states of a non-harmonic oscillator are discussed. It is shown that there are squeezing properties in these quantum states.

In this paper, we study the noncommutative deformation of different optical states. We develop the deformed coherent state by using the raising and lowering operators of the quantum harmonic oscillator. This helps us to investigate the noncommutative deformation of a squeezed state in terms of noncommutative parameter, which in turn leads to the noncommutative deformation of a photon-added coherent state. This noncommutative deformation has an overall effect on the non-classicality of such states. This is done by investigating the impact of noncommutative deformation of the Mandal parameter for such states.

Generalized q-deformation coherent states of a non-harmonic oscillator in a finite-dimensional Hilbert Space are constructed. Their amplitude-squared squeezing are discussed. The result shows that there are squeezing effects in these quantum states. The relationship between condition of squeezing and parameters S, r, q is found.
