Hello, I’m Avinto, and in this section, we’ll look at LASERs—devices that produce a highly focused beam of light with remarkable properties. We’ll start by exploring the production of LASER light, which involves the process of stimulated emission. You’ll learn about the properties of LASER light, such as coherence, monochromaticity, and directionality. We’ll also discuss the different types of LASERs and their various applications, from medical devices to telecommunications.
