We discuss saturation effects in gated photon counting, when the width of the laser pulse is several times the width of the individual anode pulses produced by ejection of a single electron at the cathode of a photomultiplier. A simple model is developed to treat the counting statistics and the results are shown to be in good agreement with experimental data. We also comment on the difficulty of establishing contact with previous work, and emphasize the difference in the domain of applicability of each approach.
