Detuning effects of FM mode-locking in atmospheric CO2 lasers
Abstract
The detuning of the intracavity FM modulation of a homogeneously broadened CO2 laser is analyzed by working in the frequency domain and by describing the field in terms of discrete amplitudes and phases. The coupled mode equations are solved for modulation frequencies near the frequency of axial mode separation, and the asymmetry of mode-locking due to the dispersive behavior of the active medium is verified experimentally. Small detuning effects are shown to have a large bearing on pulse parameters. The experimental results are in agreement with the theory.
