Coherent Optics

Coherent optics refers to the study of light that maintains a consistent phase relationship over time. This principle is crucial in nonlinear optics, where intense light can interact with materials in complex ways, generating new frequencies and patterns. By using coherent light, like that from lasers, scientists can manipulate how light behaves as it passes through different media. This has applications in telecommunications, imaging, and advanced technologies, enabling clearer signals and more efficient light-based devices. Essentially, coherent optics helps us understand and utilize the unique properties of light in innovative ways.
