Few-femtosecond phase-sensitive detection of infrared electric fields with a third-order nonlinearity
Hannes Kempf, Philipp Sulzer, Andreas Liehl +2
Measuring an electric field waveform beyond radio frequencies is often accomplished via a second-order nonlinear interaction with a laser pulse shorter than half of the field's osc…
Up to 70 THz bandwidth from implanted Ge photoconductive antenna excited by a fibre laser
Abhishek Singh, Alexej Pashkin, Stephan Winnerl +6
Phase-stable electromagnetic pulses in the THz frequency range offer several unique capabilities in time-resolved spectroscopy. However, the diversity of their application is limit…
Self-control of a passively phase-locked Er:fibre frequency comb
Andreas Liehl, David Fehrenbacher, Philipp Sulzer +5
Femtosecond frequency combs have boosted progress in various fields of precision metrology. Nevertheless, demanding applications such as front-end frequency and time standards, ult…
