摘要： The squeezed coherent thermal state is considered. Its various coherent representations, including Q-, P-and Bargmann representations are introduced. The analytic formula for the photon number distribution of such a quantum state is obtained directly from the Bargmann representation. The effects of the squeezing and the thermal noise on the photon distribution are discussed.
