Homodyne statistics of light generated by an atomic system exhibiting optical bistability are analyzed. Using the dynamical equations of motion for a single atom in a coherently driven cavity in the good cavity limit, we show that the homodyne field can be described in terms of two independent real Gaussian stochastic processes and a coherent component. By making a Karhunen-Lo\`eve expansion of the field variables we derive the generating function for the photoelectron statistics. From this generating function photoelectron-counting distribution, factorial moments, and waiting-time distribution are obtained analytically. These quantities are directly measurable in photon-counting experiments. We show that the homodyne field exhibits many interesting nonclassical features including nonclassical effects in higher-order factorial moments.
