Abstract

A novel, compact, user friendly fiber laser with a broad emission bandwidth (MenloSystems, λc=1375nm, Δλ=470nm, Pout=4mW) was used to achieve unprecedented sub-2-μm axial resolution optical coherence tomography (OCT) in nontransparent biological tissue in the 1300-nm wavelength region. Fresh human skin and arterial biopsies were imaged ex vivo with ~1.4-μm axial and ~3-μm lateral resolution and 95-dB sensitivity, demonstrating the great potential for clinical OCT applications of this stable, low-cost, and turn-on-key fiber laser.
