Abstract: A coherent anti-stokes Raman scattering apparatus for imaging a sample comprises 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 comprising two of the first, second and third optical signals is provided to the optical output for imaging the sample.
