24 Mar 2006 An ultra compact supercontinuum white light source with broadband, diffraction-limited output from the visible light to the IR (450 to beyond 2000 nm), the SuperK manufactured by KOHERAS A/S of Birkerød, Denmark, is based on a proprietary... ... compact pump laser design and a patent-pending dual wavelength pumping scheme. It also provides continuum radiation in the technologically important blue and near-UV spectral regions. Previous supercontinuum light sources that could provide this coverage were based on Ti:Sapphire-laser-pumped systems and were expensive, very large and complicated to operate. Available in a rugged turn-key system and OEM solution, the SuperK is the first and only source in the market, which is economically suitable for industrial volume application.
The NEW improved, turn-key, maintenance-free and multipurpose white light source from KOHERAS is available for only 19,995. See it at Photonic West 2006.
The turnkey light source integrates easily into instruments and systems for industrial measurement tasks and for general use as a research tool. It also is suitable for high-resolution optical coherence tomography, where it performs rapid scanning in the medical environment, and for white light interferometry, where it determines the displacement or the chromatic dispersion in fibre and planar waveguides with high accuracy. Many new exciting applications, which can use the source with great advantage are those in the biotechnololy environment like fluorescent imaging, confocal microscopy, flow cytometry just to name a few. The light source will enhance the resolution of those applications to a level which has not been seen before.
Another application is to be found in a growing market for the High Resolution 3D non contact Surface Metrology segment, where a Xenon lamp has been used before. But due to a low intensity of the Xenon lamp these system can not deliver a High Resolution image. With the new light source KOHERAS SuperK the surface metrology system can deliver an image at a much higher resolution than it has ever been shown before.
In the telecoms field using the new white light source in a simple production test setup of CWDM or DWDM filters, one can immediately analyze the dynamic range of each channel, 3dB-bandwidth, and polarization extinction ratio to adjacent channels. Last but not least with its unmatched wavelength coverage, the KOHERAS SuperK covers all O-E-S-C-L and U bands. There is no need for multiple ASE sources in the test setup.
Manufacturers of thin film filters and anti-reflections coatings have been limited in their measurement using conventional white light sources with a poor brightness of their output beam. Up until now the results of such measurements has been limited down to a -30dB whereas the new white light source from KOHERAS can easily perform a perfect measurement down to -65dB or less.
The new white light source is also ideally for measurement and testing of chromatic dispersion in fibre and planar waveguides with high accuracy.
Its output spectrum can be tailored to specific applications by changing the nonlinear photonic crystal fibre that is used to generate the continuum, offering enhanced functionality and value from the current platform.
