Emergence of Classical Radiation Fields through Decoherence in the Scully-Lamb Laser Model

  • Julio Gea-Banacloche


The quantum theory of the laser of Scully and Lamb is used to determine the longest-lived states of the quantized field in an idealized, single-mode laser cavity. It is shown that quasiclassical states (states with well-defined phase and amplitude) are naturally selected. A quantum trajectory analysis provides some insight as to why this is so.

    In fact, it has been shown quite recently that highly excited number states lead to interference patterns just as coherent states do, see J. Javanainen and S. M. Yoo, Phys. Rev.
