Abstract  We explore the theoretical possibility of extending the usual squeezed state to those produced by nonlinear single-mode squeezing operators. We derive the wave functions of exp[-(ig/2)(√1-X2P+P1-X2)]|> in the coordinate representation. A new operator's disentangling formula is derived as a by-product.
Keywords:  wave functions      nonlinear single-mode squeezed states      coordinate representation      disentangling formula
