PhD project: Super broadband FDML Laser for Optical Coherence Tomography

To achieve a high-speed and high-resolution imaging, specialized light sources are highly demanded in Optical Coherence Tomography, which sweep across broad bandwidth and allowing imaging for longer depths with high resolution. This project aims to develop a super broadband Fourier Domain Mode Locked (FDML) Laser for Optical Coherence Tomography.
