Optical frequency combs have revolutionized the field of frequency metrology within the last decade and have become enabling tools for atomic clocks, gas sensing and astrophysical…
Mode spectrum and temporal soliton formation in optical microresonators
T. Herr, V. Brasch, J. D. Jost +4
The formation of temporal dissipative solitons in optical microresonators enables compact, high repetition rate sources of ultra-short pulses as well as low noise, broadband optica…
All Optical Stabilization of a Soliton Frequency Comb in a Crystalline Microresonator
J. D. Jost, E. Lucas, T. Herr +4
Microresonator based optical frequency combs (MFC) have demonstrated promise in extending the capabilities of optical frequency combs. Here we demonstrate all optical stabilization…
Limits on Primordial Black Hole evaporation with the H.E.S.S. array of Cherenkov telescopes
J-F. Glicenstein, A. Barnacka, M. Vivier +1
Data collected by the H.E.S.S. array between 2004 and 2012 have been used to search for photon bursts from primordial black hole explosions. Bursts were searched for in a 30 second…
Very-High Energy Gamma-Ray Flux Limits for Nearby Active Galactic Nuclei
T. Herr, W. Hofmann
Combining the results of targeted observations, H.E.S.S. has accumulated a large amount of extra-galactic exposure at TeV energies. Due to its large field of view a considerable pa…
Dual-comb cavity ring-down spectroscopy
D. Lisak, D. Charczun, A. Nishiyama +10
Cavity ring-down spectroscopy is a ubiquitous optical method used to study light-matter interactions with high resolution, sensitivity and accuracy. However, it has never been perf…
Temporal solitons in optical microresonators
T. Herr, V. Brasch, J. D. Jost +4
Dissipative solitons can emerge in a wide variety of dissipative nonlinear systems throughout the fields of optics, medicine or biology. Dissipative solitons can also exist in Kerr…
