Micromasers: a quantum jump approach
E. S. Guerra, Carlos R. de Carvalho · Journal of Optics B Quantum and Semiclassical Optics · 2001
We have developed a quantum jump approach for the one photon micromaser with a Poissonian atomic pumping beam. In our approach we can describe the dynamics of the system, completely unravelling the master equation in terms of stochastic wavefunctions. We have applied the approach to the most general case in which the atoms enter the cavity in an arbitrary coherent superposition of the atomic states with different initial conditions for the cavity field. Hence, we are able to study the system dynamics when the atoms enter the cavity in the excited state and interacting initially with the field in a pure state as well as when the atoms enter the cavity in a coherent superposition with the field initially in a statistical mixture leading to the production of a cotangent state.
