Fourier Domain Mode Locking (FDML): A new laser operating regime and applications for optical coherence tomography

R. Huber, M. Wojtkowski, J. G. Fujimoto

Abstract

We describe buffered Fourier domain mode locking (FDML), a technique for tailoring the output and multiplying the sweep rate of FDML lasers. Buffered FDML can be used to create unidirectional wavelength sweeps from the normal bidirectional sweeps in an FDML laser without sacrificing sweep rate. We also investigate the role of the laser source in dynamic range versus sensitivity performance in optical coherence tomography (OCT) imaging. Unidirectional sweep rates of   over a   range at a center wavelength of   are achieved. High-speed, swept-source OCT is demonstrated at record speeds of up to 370,000 axial scans per second
