Broadband light source, which has a broadband spectrum, and a short coherence -, the measuring instrument has such a light source

摘要

The present invention relates to an arrangement for producing a wide band spectrum, which is, in particular, as a light source can be used for the short-coherence interferometry.The arrangement consists of a laser, in particular from a laser diode, for the generation of a short light pulse of the wavelength λ_p and a microstructured optical fiber (1) with a high nonlinearity, which a zero dispersion of the group velocity close to the wavelength λ_p and an anomalous dispersion, as well as means for coupling of the light pulse into the microstructured optical fiber.
