Characteristics of a Yb-doped superfluorescent fiber source for use in optical coherence tomography

M. Bashkansky, M. D. Duncan, L. Goldberg, J. P. Koplow, and J. Reintjes

Open Access Open Access

Abstract

We have used a newly developed Yb-doped high-power fiber source in an optical coherence tomography (OCT) apparatus. We have analyzed various properties of interest for OCT measurements such as spectral shape, related gate width, central wavelength, bandwidth, and power output.
