Laser Generation 101: The Core Principles Explained

Laser Generation 101 The Core Principles Explained

(1) Stimulated Emission Stimulated absorption, spontaneous emission, and stimulated emission are the three interaction processes between light and matter. As illustrated in Figure 3-1, lasers are generated through the process of stimulated emission. According to quantum theory, an energy level corresponds to an electron’s energy state, which is determined by the principal quantum number n
