Theory of Self-Locking of Lasers with Inhomogeneously Broadened Lines.

摘要

A theoretical model is given to describe self-locking. The semi-classical theory of Lamb for laser action has been modified to include the collisional effects on linewidth and on the nonlinear polarization. The collisional effects were included by a classical atom-atom rate. The results modify Lamb's equation for the frequencies and phases of oscillating modes. The criterion of self-locking of modes is expressed in terms of ratio of loss to unsaturated gain. Comparisons of the theoretical results and published experimental results for He-Ne and He-Cd are satisfactory. (Author)
