Abstract
Intracavity dipole motions are considered for the first time in the laser t heory with consistent regard for dipole-dipole interactions. These interact ions are shown to result not only in the well-known dipole dephasing but, a dditionally, give rise to cooperative coherent dipole oscillations with a c haracteristic frequency omega(osc) equal to the geometric average of the re sonant atomic frequency and average local dipole field frequency. It is als o demonstrated that it is these cooperative oscillations that are responsib le for the frequency shift (with respect to the resonance frequency) of the laser radiation by a value inherent in dipole oscillations.
