Abstract

We report on the development of a 2.5μm core photonic crystal fiber with a substantially reduced water-peak loss around 1.38μm, which allows extended Raman-soliton supercontinuum generation up to 1.55μm with a cw ytterbium fiber laser pump source. The resulting broadband, high-spectral-power-density, low-coherence light source can be employed for advanced, submicrometer resolution optical coherence tomography.
