Abstract

We investigate the basic problem of the interaction of a single quantised mode of the radiation field, modelled as quantised harmonic oscillator (HO) with a laser pulse of chirped Gaussian line-shape. The average photon number and the transient emitted spectrum are calculated analytically in terms of the error function of complex argument. The spectral peaks of the line structure of the emitted radiation are examined for different system parameters and initial states of the HO.

Keywords: Harmonic Oscillator, quantum optics, radiation, wave radiation
