This course introduces the principles of lasers and their applications in various fields. It begins with the concept of coherence, distinguishing between temporal and spatial coherence. The course then delves into the physics of lasers, including stimulated emission, population inversion, and different types of lasers such as solid-state, liquid, and gas lasers. Furthermore, it explores holography, a technique for three-dimensional photography, and fiber optics for optical communication. The course concludes by examining pulse dispersion and power loss in optical fibers.
