High-average-power femtosecond laser at 258 nm
Michael Müller, Arno Klenke, Thomas Gottschall +6
We present an ultrafast fiber laser system delivering 4.6 W average power at 258 nm based on two-stage fourth-harmonic generation in beta barium borate (BBO). The beam quality is c…
1kW 1mJ 8-channel ultrafast fiber laser
Michael Müller, Marco Kienel, Arno Klenke +5
An ultrafast fiber chirped-pulse amplifier comprising 8 coherently combined amplifier channels is presented. The laser delivers 1 kW average power at 1 mJ pulse energy and 260 fs p…
Energetic sub-2-cycle laser with 220 W average power
Steffen Hädrich, Marco Kienel, Michael Müller +12
Few-cycle lasers are essential for many research areas such as attosecond physics that promises to address fundamental questions in science and technology. Therefore, further advan…
Virtual H&E Histology by Fiber-Based Picosecond Two-Photon Microscopy
Jan Philip Kolb, Daniel Weng, Hubertus Hakert +10
Two-Photon Microscopy (TPM) can provide three-dimensional morphological and functional contrast in vivo. Through proper staining, TPM can be utilized to create virtual, H&E equival…
Confining Brownian motion of single nanoparticles in an ABELtrap
Maria Dienerowitz, Thomas Heitkamp, Thomas Gottschall +2
Trapping nanoscopic objects to observe their dynamic behaviour for extended periods of time is an ongoing quest. Particularly, sub-100nm transparent objects are hard to catch and m…
High-repetition-rate and high-photon-flux 70 eV high-harmonic source for coincidence ion imaging of gas-phase molecules
Jan Rothhardt, Steffen Hädrich, Yariv Shamir +23
Unraveling and controlling chemical dynamics requires techniques to image structural changes of molecules with femtosecond temporal and picometer spatial resolution. Ultrashort-pul…
