The introduction of supercontinuum lasers has made significant advancements for many research areas. Also for nanophononics and materials science these light sources have been key for the many developments that have been made of which NKT Photonics has been on the forefront of this innovation. These lasers combine the broad spectrum of lamps, with the brightness of lasers .
Supercontinuum generation
SuperK lasers generate a supercontinuum, a broad spectrum of light, through nonlinear interactions within photonic crystal fibers. It all begins with a mode-locked Ytterbium (Yb) fiber laser which emits picosecond pulses at 1064 nm. These pulses are amplified and fed into highly nonlinear fibers. These fibers have a small core diameter, which provides a strong spatial confinement and high nonlinear coefficients. This results in a broad single-mode beam covering a range of 390 to 2400 nm with up to 6.5W output power.
The SuperK lasers can be combined with several filter units which makes it a broadband tunable laser. These lasers are highly reliable and user-friendly. Also no maintenance is required and they have tens of thousands hours lifetime, making it suitable for various scientific and industrial applications.
Real-World Applications in Low-Dimensional Materials
Metamaterials Research
Another application is in the field of metamaterials. Metamaterials are engineered structures with properties not found in nature and are often used to manipulate electromagnetic waves. SuperK lasers are used in the experimental characterization of these materials. Achromatic metalenses, which can focus light without chromatic aberration, can for example be precisely analyzed using the tunable and stable SuperK light source. This enables the development of advanced optical devices with enhanced performance.

Tunable Excitation Source for Perovskites
Perovskite materials are gaining significant attention in the field of photovoltaics and optoelectronics. This is due to their excellent light absorption and charge transport properties. SuperK lasers, and in particular the SuperK Fianium combined with a SuperK VARIA filter unit, are used as tunable excitation source for the time-resolved analysis of exciton dynamics in perovskites. This setup you are able to do photoluminescence and photocurrent measurements but also time-correlated single photon counting (TCSPC). This allows researchers to study the fundamental properties and performance of perovskite nanocrystals.
