A multiple wavelength light source device and associated method for generating output radiation comprising a plurality of discrete output wavelength bands. The multiple wavelength light source device comprises a pump radiation source arrangement configured to generate input radiation comprising at least a first frequency component and a second frequency component; and a hollow-core photonic crystal fiber configured to confine a working medium. The hollow-core photonic crystal fiber is configured to receive said input radiation and to generate said plurality of discrete output wavelength bands distributed over a wavelength range of interest via a seed-assisted cascaded four wave mixing (FWM) process in said working medium.
