Abstract

In a homogeneously broadened CO₂laser [1] only the polarization can be adiabatically eliminated (class B lasers), so that the dynamics is ruled by two rate equations for the field and population inversion ($I=E^2/E_s^2$ is the field squared and normalized to saturation intensity $E_S^2=\frac{{\gamma }_{\perp }{\gamma }_{\text{IL}}}{4g^2},G=2g^2/{\gamma }_1$ is the coupling factor, d is the population inversion normalized to the pump value Δo, with g = wµ²/ħϵoV and γ₁, γ_ILfor the polarization and population inversion decay rates).
