Lecture
This lecture covers topics related to nonlinear optics, including second harmonic generation, electro-optical effects, third-order nonlinear optical effects, and phase conjugation. It explains phenomena such as optical rectification, frequency conversion, and four-wave mixing. The instructor discusses the response of nonlinear media to intense optical beams, the generation of new frequencies, and the self-phase modulation effect. Additionally, the lecture explores Gaussian optical pulses, group speed dispersion, and the propagation of optical pulses in dispersive media, emphasizing the optical Kerr effect and phase conjugation.
