摘要：

A superluminescent Ti: Al2O3 crystal is demonstrated as a light source for ultrahigh resolution optical coherence tomography (OCT). Single spatial mode, fiber coupled output powers of similar to40 muW can be generated with 138 nm bandwidth using a 5 W frequency doubled, diode pumped laser, pumping a thin Ti: Al2O3 crystal. Ultrahigh resolution OCT imaging is demonstrated with 2.2 mum axial resolution in air, or 1.7 mum in tissue, with >86 dB sensitivity. This light source provides a simple and robust alternative to femtosecond lasers for ultrahigh resolution OCT imaging. (C) 2002 Optical Society of America.
