Highly efficient narrowband terahertz generation driven by a two-spectral-line laser in PPLN
H. T. Olgun, W. Tian, G. Cirmi +7
We demonstrate record conversion efficiencies of up to 0.9 percent for narrowband (1 percent relative bandwidth) THz generation by strongly-cascaded difference frequency generation…
Segmented Terahertz Electron Accelerator and Manipulator (STEAM)
Dongfang Zhang, Arya Fallahi, Michael Hemmer +8
Acceleration and manipulation of ultrashort electron bunches are the basis behind electron and X-ray devices used for ultrafast, atomic-scale imaging and spectroscopy. Using laser-…
Cascaded Parametric Amplification for Highly Efficient Terahertz Generation
Koustuban Ravi, Michael Hemmer, Giovanni Cirmi +4
A highly efficient, practical approach to high-energy terahertz (THz) generation based on spectrally cascaded optical parametric amplification (THz-COPA) is introduced. The THz wav…
Strong-field physics with mid-IR fields
Benjamin Wolter, Michael G. Pullen, Matthias Baudisch +7
Strong-field physics is currently experiencing a shift towards the use of mid-IR driving wavelengths. This is because they permit conducting experiments unambiguously in the quasi-…
Formation of very low energy states crossing the ionization threshold of argon atoms in strong mid-infrared fields
Benjamin Wolter, Christoph Lemell, Matthias Baudisch +9
Atomic ionization by intense mid-infrared (mid-IR) pulses produces low electron energy features that the strong-field approximation, which is expected to be valid in the tunneling…
Self-compression to sub-3-cycle duration of mid-infrared optical pulses in bulk
Michaël Hemmer, Matthias Baudisch, Alexandre Thai +2
The generation of few-cycle pulses with controlled waveforms in the mid-infrared spectral region is a long-standing challenge but is expected to enable a new generation of high-fie…
Multi-octave supercontinuum from mid-IR filamentation in bulk
F. Silva, D. Austin, A. Thai +4
In supercontinuum generation, various propa- gation effects combine to produce a dramatic spec- tral broadening of intense ultrashort optical pulses with far reaching possibilities…
