我们演示了一种高速波长扫描激光器，其调谐范围为104 nm (1228-1332 nm)，重复频率为403 kHz。该激光器的设计采用了高精细度多边形波长扫描滤波器和短长度单向环形谐振器。利用该激光器实现了人体皮肤在体内的光学频域成像，该系统的灵敏度高于98 dB，单侧测距深度为1.7 mm，灵敏度滚降为4 dB。
We demonstrate a high-speed wavelength-swept laser with a tuning range of 104 nm (1228–1332 nm) and a repetition rate of 403 kHz. The design of the laser utilizes a high-finesse polygon-based wavelength-scanning filter and a short-length unidirectional ring resonator. Optical frequency domain imaging of the human skin in vivo is presented using this laser, and the system shows sensitivity of higher than 98 dB with single-side ranging depth of 1.7 mm over 4 dB sensitivity roll-off.
