    "abstract": "In this work we present a very simple approach to input-output relations in\noptical cavities, limiting ourselves to one- and two-photon states of the\nfield.\n  After field quantization, we derive the non-unitary transformation between\n{\\em Inside} and {\\em Outside} annihilation and creation operators. Then we\nexpress the most general two-photon state generated by {\\em Inside} creation\noperators, through base states generated by {\\em Outside} creation operators.\nAfter renormalization of coefficients of inside two-photon state, we calculate\nthe outside photon-number probability distribution in a general case. Finally\nwe treat with some detail the single mode and symmetrical cavity case.",
