摘要

We present a new design of a Fourier Domain Mode Locked laser (FDML laser), which provides a new record in sweep range at ～1μm center wavelength: At the fundamental sweep rate of 2×417 kHz we reach 143nm bandwidth and 120nm with 4× buffering at 1.67MHz sweep rate. The latter configuration of our system is characterized: The FWHM of the point spread function (PSF) of a mirror is 5.6μm (in tissue). Human in vivo retinal imaging is performed with the MHz laser showing more details in vascular structures. Here we could measure an axial resolution of 6.0μm by determining the FWHM of specular reflex in the image. Additionally, challenges related to such a high sweep bandwidth such as water absorption are investigated.
