Beschreibung
"How Lasers Work" explores the physics behind lasers, illuminating their transformative applications across technology and medicine. It begins by establishing a foundation in light and electromagnetic radiation, progressing to explain light absorption, spontaneous emission, and stimulated emission – the key to laser function. The book emphasizes the laser's unique properties, such as monochromaticity and coherence, which enable its precision applications, like cutting through steel and repairing retinas.
The book details the historical development of the laser, from Einstein's theoretical concepts to Theodore Maiman's first working laser in 1960. Different types of lasers, including gas, solid-state, and semiconductor lasers, are examined in terms of construction, principles, and specific uses. A significant portion is dedicated to laser applications in medicine, communication, and industry, providing real-world examples of their impact.
The book uses experimental data and schematics, and connects laser physics to materials science, computer science, and environmental science. It provides a balanced treatment of theory and practice, making it valuable for both academic study and practical reference.
