Description

Introduction to Nonlinear Optics and its Applications. Instructor: Prof. Samudra Roy, Department of Physics, IIT Kharagpur. Nonlinear Optics is one of the important subdisciplines of Modern Optics.

It mainly deals with the light-matter interaction when the material response is nonlinear. In the prescribed course we study the basic nonlinear optical effects (like higher harmonic generation, optical Kerr effect, self-phase modulation etc) that take place when the material is illuminated by a strong light (preferably Laser). The course offers the subject matter by giving a rigorous theoretical background and framework for a nonlinear effect, followed by details of how such an effect is implemented in real applications.
