Abstract

The invention relates to an arrangement for generating a broadband spectrum which can be used in particular as a light source for short coherence interferometry. The arrangement comprises a laser, in particular a laser diode, for generating a short light pulse of wavelength λp and a microstructured optical fiber (1) with a high nonlinearity, which has a zero dispersion of the group velocity in the vicinity of the wavelength λp and an anomalous dispersion, as well as means for introducing the light pulse into the microstructured optical fiber.
