Scott C. Buchter, Helsinki University of TechnologyBo Andersen, Koheras ASSupercontinuum sources are finding increasing use in applications that require a source with very broad spectral bandwidth and high spatial brightness. A common method of generating supercontinuum light has involved the coupling of the output from a high-power femtosecond laser into a photonic crystal, or holey, fiber, in which a variety of nonlinear optical effects contribute to extreme spectral broadening. Although effective, the use of this type of pump source results in a complicated and expensive system that heretofore has restricted it to the laboratory. In the past year, advances in...Read full articleRelated content from Photonics MediaArticlesTerahertz Generation Method Targets Ultrafast ElectronicsTerahertz (THz) waves can be used to probe the magnetic properties of new materials.
