Abstract:

To describe the interaction of laser and medium accurately, the semi-classical vector theory for elliptical mode is presented in this paper. From the self-consistent field equations, the limitations of the circular vector theory are analyzed. Based on the elliptical mode eigenvector, the elliptical vector theory formula is derived and discussed. The discussion shows that, the elliptical vector theory is in accordance with actual physics mode and has specific physics meaning, it evolves into circular vector theory when ellipticity is zero and accords with the experiment results well semi-quantitatively.

Key words: laser physics, semi-classical theory, elliptical eigenvector mode, self-consistent field equations
