Paper Abstract

Wideband light generation from a single mode optical fiber was investigated. Investigation showed that spectral structure of light broadened by self-phase modulation was not sensitive to fluctuations of the input pulse energy, and its intensity noise was much lower than that of contimuum light from a microstructure fiber. The spectral width of a femtosecond input laser pulse was successfully broadened by a factor of eleven, and a longitudinal resolution of OCT was improved from 35 to 3.7 μm. The system empoyed a dynamic focusing tracking method to maintain high lateral resolution over a large imaging depth.
