Résumé : The C(λ)-extended oscillator spectrum generating algebra is shown to be a C(λ)-extended (λ - 1)th-degree polynomial deformation of su(1,1). Its coherent states are constructed. Their statistical and squeezing properties are studied in detail. Such states include both some Barut-Girardello and the standard λ-photon coherent states as special cases.
