我们描述了缓冲傅里叶域锁模（FDML），一种用于定制输出和倍频FDML激光器的扫描速率的技术。缓冲FDML可用于从FDML激光器中的正常双向扫描创建单向波长扫描，而不牺牲扫描速率。我们还研究了激光源在光学相干断层扫描（OCT）成像中的动态范围与灵敏度性能的关系。在中心波长为1300 nm的100 nm范围内实现了370 kHz的单向扫描速率。高速扫频光源OCT以每秒高达370，000次轴向扫描的创纪录速度进行演示。(c)2006年美国光学学会。
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 370 kHz over a 100 nm range at a center wavelength of 1300 nm are achieved. High-speed, swept-source OCT is demonstrated at record speeds of up to 370,000 axial scans per second. (c) 2006 Optical Society of America.
