We present an akinetically swept light source based on a spectrally broadened mode-locked laser in all normal dispersion optical fiber followed by a linear dispersive time stretch and a regenerative amplification stage. Developed for ultrafast swept-source optical coherence tomography (SS-OCT), the source enables the demonstration of A-scan rate at 40 MHz with a 12   $\mu$  m axial resolution. Through A-scans captured from a fast-moving object, we demonstrate that high-speed OCT is possible at 1   $\mu$  m wavelength in an architecture which is not intrinsically bandwidth limited. The source therefore shows a promising route to achieving high axial resolution in high-speed swept-source OCT.
