Lecture
Nonlinear frequency conversion: sum frequency generation
Description
This lecture covers the concept of nonlinear frequency conversion, focusing on sum frequency generation (SFG) and second harmonic generation (SHG). It explains the principles behind these processes, the importance of phase matching, and the use of birefringent crystals for efficient frequency conversion. The instructor discusses the theory and modern applications of lasers in generating new wavelengths through nonlinear processes.
