1 MICRON WAVELENGTH SWEPT LASER FOR OPTICAL COHERENCE TOMOGRAPHY

摘要：

A frequency swept laser at center wavelength of 1060 nm for Fourier domain optical coherence tomography (FDOCT) was demonstrated. The laser is composed of a fiber-coupled semiconductor optical amplifier (SOA) gain module, a fiber Fabry-Perot tunable filter (FFP-TF), fiber isolators and couplers to form a uni-directional ring laser. The laser is capable of a scanning range of 64 nm and coherence length of 9.8 mm at 2 KHz sweep rate.With the built swept source, a FDOCT system was developed which can achieve 12 μm axial resolution in tissue. Imaging of pig retina was demonstrated with the FDOCT system.
