NEW NONLINEAR OPTICAL EFFECTS IN EMISSION AND ABSORPTION OF INDIVUDUAL RESONANCE PHOTONS BY TWO LEVEL ATOMS TRAPPED IN DAMPED MICROCAVITY

Abstract

The new cooperative nonlinear effects in emission and absorption of resonance photon by two level atoms trapped in damped single-mode one-dimensional microcavity have been revealed and investigated nonpertubatibely. Two cases have been considered: the case of an excited ultracold atom localized initially in the ground vibrational state of the trap's parabolic well and the case of one and two two level motionless atoms in diferent initial states. The dynamics and spectrum of emission (absorption) have been shown to be determined in particular by o --the rate of decaying of mode in the empty cavity. The gigantic optical effect has been discovered under resonance condition \omega _v=2g . Out of this condition there arise numerous resonances of the higher order on different frequencies so that one thermal impulse has been observed instead of the Moessbauer peak. In the case of two motonless atoms non-emitting (dark) antisymmetric and emitting (luminous) symmetric atomic superpositional...
