"High-speed frequency swept light source for Fourier domain OCT at 20 kHz A-scan rate" R. Huber, K. Taira, M. Wojtkowski, T. H. Ko, J. G. Fujimoto, K. Hsu,Proceedings-of-the-SPIE-The-International-Society-for-Optical-Engineering. 2005; 5690(1): 96-100 Abstract: We demonstrate a high-speed tunable, continuous wave laser source for Fourier domain OCT. The laser source is based on a fiber coupled, semiconductor optical amplifier and a tunable ultrahigh finesse, fiber Fabry Perot filter for frequency tuning. The light source provides frequency scan rates of up to 20,000 sweeps per second over a wavelength range of >70 nm FWHM at 1330 nm, yielding an axial resolution of approximately=14 mu m in air. The linewidth is narrow and corresponds to a coherence length of several mm, enabling OCT imaging over a large axial range.
