Newport Unveils Supercontinuum Laser Device

Newport has introduced a coherent anti-stokes raman scattering (CARS) optimised supercontinuum generation fibre device. Designed for use with 800nm femtosecond lasers, the SCG-800-CARS contains 12cm, highly nonlinear photonic crystal fibre with zero-dispersion points at 775nm and 945nm.

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 nonlinear supercontinuum fibre is mounted in a robust, 25mm diameter, 120mm-long aluminum housing that can be mounted on a translation stage.

The pre-assembled product features a sealed end facet with beam expansion for easy coupling, making it suitable for spectroscopy and microscopy applications. The SCG-800-CARS will be exhibited at Newport's booth during SPIE Photonics West, from 26-28 January at the Moscone Center, San Francisco. It will be demonstrated as part of a Newport 'Wavelength Extension Unit for Ultrafast Oscillators' kit.
