What Does THG Stand For?
THG stands for Third Harmonic Generation
THG, or Third Harmonic Generation, is a nonlinear optical process that occurs when a material interacts with intense laser light, resulting in the generation of new photons with three times the frequency (or one-third the wavelength) of the original light. This phenomenon is utilized in various applications, including the production of ultraviolet light sources, in optical communication systems, and in scientific research to probe and manipulate material properties at the atomic and molecular levels. THG is significant for its ability to enhance signal levels and enable the study of ultrafast processes in materials.
