| Video Discription | LASERS Session 1 (Spontaneous Emission, Stimulated Emission, Light Amplification) *What does LASER stand for? In what respect it differ from an ordinary source of light? *How LASERs are different compared to X-rays? *Differentiate between spontaneous emission and stimulated emission of radiation. *Define absorption. What is its role in a laser system? *What is population inversion? Explain its significance in the operation of LASER. *What is pumping in laser? Mention the types of pumping methods. *Differentiate between stimulated emission and spontaneous emission. *What is the role of resonant cavity in the operation of laser? *Define – absorption, spontaneous emission, stimulated emission, metastable state, population inversion Notes on this topic are available here : https://drive.google.com/file/d/1AHQQdLA1KqJ4ayCfIuRfmPwzceCbHMn1/view?usp=sharing |
