Jens Limpert awarded for his pioneering research by the ERC for the 3rd time

With one of the EU's highest endowed grants the European Research Council (ERC) is supporting basic research at the Institute of Applied Physics (IAP) for the fourth time already.

Describing the significance of these ERC Grants, it should be noted that only "pioneering research" is funded and scientific excellence is the sole selection criterion. Prof. Jens Limpert was one of the first to obtain not only a "Starting Grant" (2009) but also a "Consolidator Grant" (2014) and now the "Advanced Grant". In Germany he is even the only one with such a "series".
Andreas Tünnermann's work on laser development was also honored with an "Advanced Grant" (2014). This proves that the IAP has achieved outstanding results in the field of laser sources and their applications, and that this is also recognized beyond the borders of Thuringia and Germany.
Now the EU is investing almost 2.5 million euros in the "SALT" project (High-Flux Synchrotron Alternative Driven by Powerful Long-Wavelength Fiber Lasers) over the next five years. Jens Limpert and his team would like to expand the application possibilities of high-performance particle accelerators (synchrotrons) by operating frequency-converted fiber lasers in every common laser laboratory in order to simplify the experimental search for answers to innovative questions. Jens Limpert describes the challenge as follows: "High-power radiation sources such as synchrotrons are characterized by their very wide frequency range (from THz to X-rays), which stretches the fields of application to such an extent that revolutionary advances in science and technology have been made possible. However, the use of such synchrotrons is very expensive due to their dimensions and operating costs, so that access to these large-scale research facilities is severely restricted and their performance potential can thus never be fully exploited. On the other hand, the spectral range of direct laser emission is limited".

This is to be solved by non-linear frequency conversion of a high-power ultrashort pulse solid-state laser. In addition, highly interesting wavelength dependencies of frequency conversion will be investigated and exploited to generate a hitherto unthinkable high photon flux in the important spectral ranges of the mid-infrared, THz and soft X-ray regions. This enables nothing less than a multitude of forward-looking discoveries and breakthroughs, such as novel approaches for the non-destructive investigation of complex materials or the detection of diseases in living organisms using state-of-the-art spectroscopy.
Furthermore, shifting the emission to longer wavelengths can release a hidden power scaling potential of fiber lasers by relaxing nonlinear and thermal constraints. If this could be achieved, it would mean a revolution in the power level of ultrashort pulse fiber lasers. "I am deeply convinced that Thulium-doped fiber lasers emitting at around 2μm wavelength will outperform and replace the mature and record-holding Ytterbium-doped counterparts in the future," says Jens Limpert.
