Towards direct nonlinear compression of energetic sub-nanosecond pulses to the ultrafast regime
Gaspard Beaufort, Nayla Jimenez, Gunnar Arisholm +5
Applications of terawatt-class lasers can enormously benefit from pulse trains with kHz repetition rates. The associated unprecedented combinations of peak and average powers requi…
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
Anne-Lise Viotti, Chen Li, Gunnar Arisholm +4
Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers ar…
Multi-gigawatt peak power post-compression in a bulk multi-pass cell at high repetition rate
Ann-Kathrin Raab, Marcus Seidel, Chen Guo +5
The output of a 200 kHz, 34 W, 300 fs Yb amplifier is compressed to 31 fs with > 88 % efficiency to reach a peak power of 2.5 GW, which to date is a record for a single-stage bulk…
Generation of 1.5-octave intense infrared pulses by nonlinear interactions in DAST crystal
Carlo Vicario, Balazs Monoszlai, Gunnar Arisholm +1
Infrared pulses with large spectral width extending from 1.2 to 3.4 um are generated in the organic crystal DAST (4-N, N-dimethylamino-4-N-methylstilbazolium tosylate). The input p…
Reciprocity and the scattering matrix of waveguide modes
Guro K. Svendsen, Magnus W. Haakestad, Johannes Skaar
The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed…
Inverse scattering of dispersive stratified structures
Johannes Skaar, Magnus W. Haakestad
We consider the inverse scattering problem of retrieving the structural parameters of a stratified medium consisting of dispersive materials, given knowledge of the complex reflect…
