N2 - This paper presents a Fourier domain mode locked (FDML) laser centered around
840 nm. It features a bidirectional sweep repetition rate of 828 kHz and a spectral bandwidth of
40 nm. An axial resolution of ∼9.9 µm in water and a 1.4 cm sensitivity roll-off are achieved.
Utilizing a complex master-slave (CMS) recalibration method and due to a sufficiently high
sensitivity of 84.6 dB, retinal layers of the human eye in-vivo can be resolved during optical
coherence tomography (OCT) examination. The developed FDML laser enables acquisition
rates of 3D-volumes with a size of 200 × 100 × 256 voxels in under 100 milliseconds. Detailed
information on the FDML implementation, its challenging design tasks, and OCT images obtained
with the laser are presented in this paper.
