摘要
A novel, compact, user friendly fiber laser with a broad emission bandwidth (MenloSystems, lambda(c) = 1375 am, Deltalambda = 470 nm, P-out = 4 mW) was used to achieve unprecedented sub-2-mum 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 similar to1.4-mum axial and similar to3-mum 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.
