Frequency doubling is a phenomenon where the frequency of a wave is doubled, often achieved through nonlinear optical processes such as second harmonic generation. This is a crucial technique in laser optics for converting laser light to different wavelengths, enabling various applications in fields like telecommunications and medical imaging.

nonlinear optical processes

Second harmonic generation (SHG) is a nonlinear optical process where two photons with the same frequency interact with a nonlinear material to produce a new photon with twice the energy, or frequency, of the initial photons. This phenomenon is widely used in laser technology to convert laser light to shorter wavelengths and is a fundamental tool in studying the properties of materials at the molecular level.
