    "abstract": "We develop a general theory of adiabatic output coupling from trapped atomic\nBose-Einstein Condensates at finite temperatures. For weak coupling, the output\nrate from the condensate, and the excited levels in the trap, settles in a time\nproportional to the inverse of the spectral width of the coupling to the output\nmodes. We discuss the properties of the output atoms in the quasi-steady-state\nwhere the population in the trap is not appreciably depleted. We show how the\ncomposition of the output beam, containing condensate and thermal component,\nmay be controlled by changing the frequency of the output coupler. This\ncomposition determines the first and second order coherence of the output beam.\nWe discuss the changes in the composition of the bose gas left in the trap and\nshow how nonresonant output coupling can stimulate either the evaporation of\nthermal excitations in the trap or the growth of non-thermal excitations, when\npairs of correlated atoms leave the condensate.",
