An all-solid-state Kerr-lens mode-locked Cr:forsterite laser operating at 1.28 µm is demonstrated as a shortcoherence-length, high-average-power source for optical coherence tomographic (OCT) imaging. We achieve ultrahigh resolution by spectrally broadening the laser pulses, using self-phase modulation in a dispersionshifted single-mode fiber. OCT imaging with a resolution of 6 µm and a dynamic range of 115 dB is achieved.
