Abstract: An optical pulse generator arranged to generate an initial sequence of optical pulses having an initial inter-pulse period; and an optical pulse burst formation apparatus including: an interleaving stage to receive an initial sequence of optical pulses having an initial inter-pulse period, including: an optical splitter to power split received optical pulses, thereby generating a first and second replica sequences of optical pulses; a first optical arm to receive the first replica sequence, having a first optical path length; and a second optical arm to receive the second replica sequence, having a second optical path length, different to the first optical path length by a path length difference; and an optical combiner arranged to combine the first replica sequence of pulses and the second replica sequence of delayed pulses to form an output sequence of optical pulse bursts.

Abstract: A coherent anti-stokes Raman scattering apparatus for imaging a sample includes an optical output; an optical source arranged to generate a first optical signal at a first wavelength; and a nonlinear element arranged to receive the first optical signal, where the nonlinear element is arranged to cause the first optical signal to undergo four-wave mixing on transmission through the nonlinear element such that a second optical signal at a second wavelength and a third optical signal at a third wavelength are generated, wherein an optical signal pair including two of the first, second and third optical signals is provided to the optical output for imaging the sample.
