Abstract
Publisher Summary This chapter investigates the quantum statistical properties and the measurable photocount statistics of radiation in the random and nonlinear media methods of quantum optics, particularly the coherent state technique, as mainly developed in the quantum theory of coherence and its applications. The chapter reviews the statistical properties of the superposition of coherent and chaotic fields of arbitrary temporal and spatial spectral composition. The treatment of the statistical properties of radiation propagating through random media, particularly through the turbulent atmosphere and Gaussian media, is also discussed in the chapter. A quantum-dynamical description is developed in the chapter, with the help of the coherent-state techniques and the Heisenberg approach (Heisenberg–Langevin equations and quantum antinormal characteristic function and related quasidistribution) or Schrodinger approach (master and generalized Fokker–Planck equations). The chapter discusses the quantum statistical properties of radiation in nonlinear optical processes, such as the optical parametric processes and the Raman and hyper-Raman scattering processes.
