Abstract:
The invention relates to the field of light sources, more specifically to a light source generating a super continuum spectrum. The invention further relates to a system for, use of and a method of generating a super continuum spectrum. An object of the present invention is to provide a super continuum light source. The invention is embodied by a super continuum source comprising: a) an amplifier section comprising a length of a large-mode area (LMA) micro-structured, double clad amplifying fibre comprising a core region, inner and outer cladding regions wherein the outer cladding region comprises a ring of air holes, and wherein a numerical aperture of the inner cladding region being larger than 0.4, and b) a coupling section, and c) a non-linear section comprising a length of a small-mode field diameter non-linear fibre. The relatively low non-linearity in the amplifier section together with the relatively highly non-linear fibre of the non-linear section enables the generation of a super continuum covering the UV and the visible wavelength range using pico-second pulses. The invention may e.g. be used in applications ranging from spectroscopy to ultra-short-pulse generation, including optical radar and ranging (LIDAR)1 spectroscopy, optical computing, and reaction rate studies.
