    "abstract": "Accurate calibration of photodetectors both in analog and in photon-counting\nregime is fundamental for various scientific applications, which range from\n\"traditional\" quantum optics to the studies on foundations of quantum\nmechanics, quantum cryptography, quantum computation, etc. In this paper we\nsystematically study the possibility of the absolute calibration of analog\nphoto-detectors based on the properties of parametric amplifiers. Our results\nshow that such a method can be effectively developed with interesting possible\nmetrological applications.",
