Paper Abstract

We report a broad-band continuum light source with high power, low noise and a smooth spectrum centered at 1.15 &mgr;m for ultrahigh-resolution optical coherence tomography (OCT). The continuum is generated by self-phase modulation using a compact 1.059 &mgr;m femtosecond laser pumping a novel photonic crystal fiber, which has a convex dispersion profile with no zero dispersion wavelengths. The emission spectrum ranges from 800 to 1300 nm and results in a measured axial resolution of ~2.8 &mgr;m in air. We demonstrate ultrahigh-resolution OCT imaging of biological tissue using this light source.
