Owing to the low scattering in biological tissues, the broadband 2 µm light source enables enhanced penetration depth, making it a compelling candidate for optical coherence tomography (OCT). In this study, we developed a polarization-maintaining (PM), all-fiber ultrashort pulse fiber laser to generate a highly stable supercontinuum (SC) light in the 2 µm band. Utilizing this SC light as the source for time-domain OCT (TD-OCT), we achieved a high sensitivity of 97 dB, demonstrating its potential for high-performance OCT applications.
