Abstract

This paper describes the development of a broad-band light source for the use in an optical coherence tomographic system. The broad-band light was generated via stimulated Raman scattering in a single-mode SiO₂ optical fiber pumped by a conventional nano-second solid state laser. A band-width of approximately 400 nm was obtained using a 500 m long single-mode SiO₂ optical fiber with a pump energy of 0.6 mJ. The longitudinal resolution of 1.8 μm was achieved when the fiber Raman laser was used as a light source in a Michelson interferometer.
