Abstract: Combined with the characteristics of Optoelectronic Information Science and engineering specialty and taking the derivation of “light” and “Gaussian beam” as an example, this paper explores the teaching of the internal relationship of the theoretical model of light transmission in free space. Practice has proved that this method is very necessary for students to understand the follow-up courses on light transmission, and provides a certain reference for the teaching of basic theory courses of engineering specialty.

Key words: electrodynamics, wave optics, geometrical optics, laser optics, optoelectronic information science and engineering
