Second Order Nonlinear Effects in Isotropic Media

This lecture from NPTEL-NOC IITM, delivered by Prof. Sivarama Krishnan (Indian Institute of Technology Madras), Prof. Pranawa Deshmukh and Prof. Vinay Pramod (both from Indian Institute of Technology Tirupati), explores the origin of second order nonlinear effects in isotropic media. Understand the fundamental principles and mechanisms behind these nonlinear optical phenomena through this 28-minute presentation, which forms part of a broader physics curriculum focused on nonlinear optics.
