Quantum cascade laser femtosecond pulses for supercontinuum generation
(2022)OSA Technical Digest ~ Conference on Lasers and Electro-OpticsIn this work, we demonstrate the generation of 630 fs, 4.5 W pulses from a mid-infrared quantum cascade laser by gain modulation induced spectral broadening and external pulse compression. Such sources open new pathways for broadband supercontinuum generation in the mid-infrared.Other Conference Item -

RF-Injection Controlled Quantum Cascade Lasers
(2022)OSA Technical Digest ~ Conference on Lasers and Electro-OpticsWe demonstrate the manipulation of the quantum cascade laser output state using microwave-injection. In the spectral domain, the optical bandwidth can be doubled, whereas in the time-domain, we observe narrow, approximately 1 ps wide features.Other Conference Item -
RF-Injection Controlled Quantum Cascade Lasers
(2022)Technical Digest Series ~ Optica High-brightness Sources and Light-driven Interactions Congress 2022In this work, we control the quantum cascade laser output state using microwave modulation. We demonstrate doubling of the spectral bandwidth as well as the generation of very narrow, approximately 1 ps wide features.Other Conference Item -

High-Resolution Rotational Fourier-Transform Infrared Spectroscopy
(2022)2022 47th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz)We demonstrate a rotational optical delay line for Fourier transform infrared (FTIR) spectroscopy with simultaneous high time and frequency resolutions. Thanks to the rotational motion, the trade-off between speed and spectral resolution present in rapid-scan FTIRs is alleviated, and enables the use of high-brightness quantum cascade laser frequency combs as light sources. We demonstrate the capabilities of the delay line by resolving ...Other Conference Item -
