Free-Running Ring Quantum Cascade Laser with 50 kHz Linewidth
Alexandre Parriaux, Ina Heckelmann, Mathieu Bertrand +3
We report on the noise characterization of a free-running ring quantum cascade laser resonator emitting a single frequency mode around 7.7 m. Using a gas cell filled with NO…
Fast and compact time-resolved spectroscopy enabled by Quantum Walk Combs
Ina Heckelmann, Davide Pinto, Uwe Schmitt +2
Optical frequency combs paved the way for fast and compact multi-component optical chemical analysis due to their broadband spectra. Dual-comb spectrometers embody this technology,…
Time-resolved spectroscopy of noise-driven collective states of light
Diego Piciocchi, Ina Heckelmann, Alexander Dikopoltsev +6
We study a collective liquid state of light in a fast-gain laser. Controlled temporal noise on the cavity modulation creates a fluctuating linear potential along the synthetic freq…
Spectral shaping of fast-gain frequency combs through phases in synthetic dimensions
Diego Piciocchi, Alexander Dikopoltsev, Ina Heckelmann +3
Optical frequency comb devices have unlocked new capabilities in telecommunications, sensing, and metrology. Yet, precise in situ control of the comb spectral envelope remains extr…
