The equal-order Y-squeezing effects of photon field for the excited two-mode squeezed vacuum state a+mb+m|ξ) are numerically studied. It is shown that the photon field can exhibit the equal-order K-th power Y-squeezing effects (K = 1. 2,3,4, 5,…), and as m increases, the equal-order K-th power Y-squeezing effects increase.
