Abstract

The laser dynamics arising from quasi-resonant interaction between a single mode field and a medium with a homogeneously broadened gain line is described by the equations coupling five variables, namely, the complex field amplitude E, the complex medium polarization P and the real population inversion D. At resonance, E and P are real and the equations reduce to where k, γ₁ and γ₁₁ are the relaxation rates of field, polarization and population, respectively, and D₀ is the population imposed by the pump.
