摘要

本文评估了采用快速强度调制器和啁啾光纤布拉格光栅构建色散调谐模式锁定扫频激光器（DTML-SS）的可行性，该激光器用于 850 nm 波长的 OCT。通过向调制器施加 1 GHz 的 50 ps 脉冲，实现了稳定的模式锁定，在 10 KHz 扫频和 1 mm 轴向范围内获得了 35 nm 的调谐范围。

Dispersion-Tuned Mode-Locked Laser for Swept Source OCT at 850 nm Using a cFBG and the Pulse Modulation Technique

In this paper, the feasibility of employing a fast intensity modulator and a chirped fibre Bragg grating to build a dispersion-tuned mode-locked swept laser (DTML-SS) for OCT at 850 nm is evaluated. Stable mode-locking is achieved by applying 50 ps pulses at 1 GHz to the modulator, obtaining 35 nm tuning range at 10 KHz sweep rate and 1 mm axial range.
