NIR/VIS dual-comb spectroscopy comparing high and low repetition rate regimes
Alexander Eber, Mithun Pal, Lukas Fürst +4
Dual-comb spectroscopy enables broadband analysis of key molecules with unparalleled frequency resolution and exceptional signal-to-noise ratios across various spectral regions. Ho…
Streaming Self-Corrected Dual-Comb Spectrometer
Alexander Eber, Christoph Gruber, Martin Schultze +2
We radically simplify coherently averaged dual-comb spectroscopy by introducing a real-time self-correction system: a radio frequency system-on-chip computes each incoming dual-com…
Ultra-resolution photochemical sensing
Lukas Fuerst, Alexander Eber, Mithun Pal +6
Photochemistry in the earth's atmosphere is driven by the sun, continuously altering the concentration and spatial distribution of pollutants. Precisely monitoring their atmospheri…
Phase-locked feed forward stabilization for dual comb spectroscopy
Mithun Pal, Alexander Eber, Lukas Fürst +3
Sustained mutual coherence between two combs over extended periods is a prerequisite for dual-comb spectroscopy (DCS), particularly in achieving high-resolution molecular spectrosc…
Ultra-broadband UV/VIS spectroscopy enabled by resonant dispersive wave emission of a frequency comb
Adrian Kirchner, Alexander Eber, Lukas Fürst +4
We introduce a novel ultra-broadband ultraviolet and visible frequency comb light source covering more than 240 THz by resonant dispersive wave emission in a gas-filled hollow-core…
