Ultrafast High-Performance Fiber Lasers for Scientific Applications

Prof. Jens Limpert | Friedrich Schiller University Jena

talks about

Various applications ask for ultrafast lasers with higher repetition rates, higher peak powers, shorter pulses and alternative emission wavelengths than available today. In that context, I will review the basics, the achievements and perspectives of fiber-based amplification of ultrashort laser pulses at 1µm and 2µm wavelength, including new waveguide designs and advanced coherent beam combination techniques. Pulse post-compression allows to shorten the pulses down to few-cycle duration, most recent results employing gas-filled capillaries and multi-pass cells in the visible, the near-infrared as well as the short-wave infrared spectral region will be discussed. Finally, applying theses primary sources as frequency conversion driver to the EUV, the mid-IR and the THz region enables high flux secondary sources. A few highlights will be presented.
