Spontaneous Emission with Induced Transitions Taken into Accountom in excited states decreases exponentially with time and, consequently, the spontaneous emission line has a dispersion form. It was shown in Chapter I that the kinetics of the decay of excited states of an atom in a strong electromagnetic field is substantially different from the case for an isola

Induced Emission and Absorption of a “Weak” Field in the Presence of a “Strong” Field by the term ?V.Q. A weak field, in contrast to a strong one, is a field which does not affect the mean populations of the levels m, n. This means that the system of equations (7.1) has to be solved in a first approximation in V.. However, as distinct from Chapter II, we are now interested in the di

Monochromatic Generation it does not absorb, but emits electromagnetic waves. Hence, for such a medium solutions which do not increase in time are impossible in the linear approximation. The limitation on the increase in field may be due to the fact that the current induced by the field depends nonlinearly on the field. Ph

Stability of Monochromatic Generatione width of the spontaneous emission line. This applies to lasers using gases or solids. In the case of gases the theoretical interpretation of this effect raises no difficulties [26], since in gases the width of the spontaneous emission line depends mainly on the Doppler effect (“inhomogeneous” broa

Electrodynamics of Lasers with an Open Resonator and Inhomogeneous Fillinghis ease that the complex dielectric constant of the active medium filling the resonator is homogeneous in space. However, the inhomogeneity of the crystals used in real lasers, the unsteady output, and pumping inhomogeneity have the result that the real and imaginary parts of the complex dielectric
