Abstract: A supercontinuum light source can comprise a seed laser arranged to provide seed pulses with a pulse frequency Fseed; a pulse frequency multiplier (PFM) arranged to multiply the seed pulses by converting pulses having the pulse frequency Fseed to pump pulses with a pulse frequency Fpump, where Fpump is larger than Fseed; and a non-linear element arranged to receive said pump pulses and convert said pump pulses to pulses of supercontinuum light. The PFM can further comprise a splitter for splitting pulses into first and second sub beams each having the same pulse frequency, where the PFM is configured such that the sub beams experience different delays; and a combiner for combining said first and second sub beams into a beam having the pulse frequency that is greater than said same pulse frequency. The splitter can have an uneven splitter ratio. The disclosure includes other embodiments as well.

Abstract: A supercontinuum light source comprising an intermediate supercontinuum light source and a single mode coupling unit, an optical measurement system comprising such light source, as well as a method of measuring are described. The supercontinuum light source comprises a pulse frequency multiplier to increase the repetition rate and the single mode coupling unit is arranged to dampen and shape the spectrum from the intermediate supercontinuum light source to allow measurements with a reduced noise floor.
