The Science of Light Amplification: An Extensive Laser Course

The Science of Light Amplification: An Extensive Laser Course. Instructor: Prof. Paramita Deb, Department of Physics, IIT Bombay. The lectures will introduce different types of lasers invented and developed till now. The underlying principles will be interwoven as the lectures progress. Some of the principles that will be covered are linear optics, non-linear optics, Stimulated emission, population inversion, and optical resonators. Laser applications in Industry and medicine and other fields of science. Also an introduction to Ultrafast laser systems and attosecond physics. (from nptel.ac.in)
