Abstract
A high-speed, broadband Fourier domain mode-locked (FDML) wavelength swept source at center wavelength of 1300 nm for high-resolution and high-speed Fourier domain optical coherence tomography was demonstrated. With two semiconductor optical amplifiers as gain media, the laser is capable of FWHM tuning range of more than 135 nm and the edge-to-edge scanning range of more than 160 nm at 45.6 kHz sweeping rate. The peak power is 11.4 mW for both the forward and backward scans. With the built swept source, a FDOCT system was developed which can achieve 6.6 μm axial resolution in air.
