Abstract

According to the transmission theory for elliptical Gaussian beam and the boundary condition of threshold beam spot, the relationship equations between the major and micro half (axises of ellipse with range), which determine the space shape of threshold beam spot, are derived. Extinction parameter and extinction function are introduced properly, which makes the maximum half-axis equation of threshold beam spot in this article is more reasonable than that in ADA 102276.
