Resumen:
We consider the problem of an atomic three-level system (in a ladder configuration) interacting witha radiation field. Assuming a coherent state as the initial state, we solve exactly the time evolution ofthe system. We discuss the appearance of atomic squeezing and calculate the atomic spin squeezingand the atomic entropy squeezing. We show that both parameters predict similar angular and timedependences.Keywords: atomic squeezing, atomic entropy squeezing, three-level atoms.
