Optical Science




Researchers in optical physics use and develop light sources that span the Electromagnetic Spectrum from Microwave s to X-ray s. The field includes the generation and detection of light, linear and Nonlinear optical processes, and Spectroscopy . Laser s and Laser Spectroscopy have transformed optical science. Major study in optical physics is also devoted to Quantum Optics and Coherence , and to Femtosecond optics. In optical physics, support is also provided in areas such as the nonlinear response of isolated atoms to intense, ultra-short electromagnetic fields, the atom-cavity interaction at high fields, and quantum properties of the electromagnetic field.
Other important areas of research include the development of novel optical techniques for nano-optical measurements, Diffractive Optics , Low-coherence Interferometry , Optical Coherence Tomography , and Near-field Microscopy . Research in optical physics places an emphasis on ultrafast optical science and technology. The applications of optical physics create advancements in Communications , Medicine , Manufacturing , and even Entertainment .
