What Does EFISH Stand For?

EFISH stands for Elec Field Induced 2nd Harmonic Generation

EFISH, or Elec Field Induced 2nd Harmonic Generation, refers to a nonlinear optical phenomenon where the application of an external electric field enhances the generation of second harmonic waves during nonlinear interaction with materials. This effect is utilized in various scientific and technological applications, including frequency conversion, imaging, and signal processing, enabling the exploration and manipulation of light-matter interactions at the quantum level.
