    "abstract": "Short pulses of a probe laser have been used in the past to measure whether a\ntwo-level atom is in its ground or excited state. The probe pulse couples the\nground state to a third, auxiliary, level of the atom. Occurrence or absence of\nresonance fluorescence were taken to mean that the atom was found in its ground\nor excited state, respectively. In this paper we investigate to what extent\nthis procedure results in an effective measurement to which the projection\npostulate can be applied, at least approximately. We discuss in detail the\ncomplications arising from an additional time development of the two-level\nsystem proper during a probe pulse. We extend our previous results for weak\nprobe pulses to the general case and show that one can model an ideal\n(projection-postulate) measurement much better with a strong than a weak probe\npulse. In an application to the quantum Zeno effect we calculate the slow-down\nof the atomic time development under n repeated probe pulse measurements and\ndetermine the corrections compared to the case of n ideal measurements.",
