Newport Corporation has introduced a new coherent anti-Stokes Raman scattering optimised supercontinuum generation fibre device, the SCG-800-CARS, which has been designed for use with 800 nm femtosecond lasers and contains 12 cm non-linear crystal fibre with zero dispersion points at ~775 nm and 945 nm.

Two closely-spaced, zero dispersion wavelengths enable a stable, low-noise supercontinuum generation that also allows control of the spectral shape by tuning the pump wavelength. The fibre ends are sealed and mounted in quartz ferrules, with the polarisation axis aligned to a line on the end of the device. The non-linear supercontinuum fibre is mounted in a robust, 25 mm × 120 mm aluminium housing which can be mounted on a translation stage. The pre-assembled product features a sealed end-facet with beam expansion for easy coupling, making it a suitable turnkey solution for spectroscopy and microscopy applications.
