The operational characteristics of an ultra-broadband light source using the stimulated Raman scattering in a single-mode optical fiber for the application to optical coherence tomography is described. The ultra-broadband output light covering from 770 nm to 1650 nm was obtained using a 500-m-long single-mode phosphorus-doped Si02 optical fiber pumped by a self Q-switched Ti: sapphire laser with a spectral width of 13 nm. When a white-light Michelson interferometer was constructed using the fiber Raman laser as a light source, a longitudinal spatial resolution of 1.7 μm was achieved.
