Abstract
A source of optical supercontinuum radiation comprises a length of microstructured optical fiber and a pump laser, the pump laser adapted to generate lasing radiation having a pump wavelength in the wavelength range of 900 nm to 1200 nm for generating an optical supercontinuum, the length of microstructured optical fibre comprising a core region having a diameter in the range of 1 μm to 5 μm and a cladding region which surrounds the core region; the cladding region comprising at least two capillary air holes having substantially the same diameter and which extend substantially along the length of the fibre; the fiber comprising a zero dispersion wavelength within ±200 nm of said pump wavelength; wherein the length of microstructured fiber can support a plurality of modes at said pump wavelength; and wherein said lasing radiation at said pump wavelength is launched into said core region of said length of microstructured optical fiber to excite the fundamental mode of the fiber. In one practice, the source of optical supercontinuum radiation does not include a pump laser arranged for generating the optical supercontinuum and pumping said length of microstructured optical fiber at a wavelength different from a wavelength within the wavelength range.
