Abstract: A frequency swept laser source for TEFD-OCT imaging includes an integrated clock subsystem on the optical bench with the laser source. The clock subsystem generates frequency clock signals as the optical signal is tuned over the scan band. Preferably the laser source further includes a cavity extender in its optical cavity between a tunable filter and gain medium to increase an optical distance between the tunable filter and the gain medium in order to control the location of laser intensity pattern noise. The laser also include a fiber stub that allows for control over the cavity length while also controlling birefringence in the cavity.

Abstract translation: 用于TEFD-OCT成像的频率扫描激光源包括具有激光源的光学台上的集成时钟子系统。 当光信号在扫描带上调谐时，时钟子系统产生频率时钟信号。 优选地，激光源还包括在可调谐滤波器和增益介质之间的光腔中的腔体延长器，以增加可调谐滤波器和增益介质之间的光学距离，以便控制激光强度图案噪声的位置。 该激光器还包括一个纤维短截线，其允许控制腔体长度，同时还控制空腔中的双折射。
