Abstract:
1. An optical coherence tomography appliance comprising: a light source which has a broadband spectrum, said light source comprising: a laser diode for generating a short light pulse of wavelength λ a microstructured optical fiber having a zero dispersion of the group velocity in the vicinity of the wavelength λ means for directing the short light pulse from the laser diode into the microstructured optical fiber; and means for measuring an optical coherence tomography of a material or structure, based on the short light pulse received by the microstructured optical fiber, wherein the microstructured optical fiber comprises a nonlinear optical material having at least one material selected from the group consisting of a multicomponent glass-ceramic, an oxidic multicomponent glass-ceramic, a nonlinear optical material made from a single-crystal material, a polycrystalline material, a liquid-crystal material, and a heavy flint glass, and wherein the heavy flint glass comprises SiO
