Abstract

We report a discrete-frequency Fourier domain mode-locked (DF-FDML) laser with uniform k-space distribution for OCT imaging. The uniform-k discrete frequencies were generated by incorporating a Fabry-Perot interferometer inside a conventional FDML cavity. OCT imaging of biological tissues was demonstrated using a prototype FD-FDML with 10mW output power, 20 kHz scanning rate, −110dB sensitivity and 12 µm axial resolution. The sensitivity exhibited no degradation throughout a ranging depth of 6 mm.
