Since first demonstrated in 2014, the technique of quantum cascade laser (QCL) dual-comb spectroscopy has developed into a beneficial tool for a variety of mid-infrared applications. By steadily improving the technology of dual-frequency-comb QCLs, researchers have been able to access the enormous potential of this technique. QCL dual-comb spectroscopy began with highly time-resolved (250 µs to 250 ms) single-shot measurements and has progressed to time scales that can compete with rapid-scan Fourier-transform infrared spectroscopy (from 1 ms to minutes). Recent research has discovered a high-spectral resolution feature within this technique that allows measurements with less than 1 MHz resolution over a bandwidth of 50 cm-1. This breakthrough was achieved by combining the high time-resolved mode with the highspectrally resolved mode in supersonic beam measurements.
Andreas Hugi explains the technical background of these acquisition modes and links them to real-world applications. These applications include protein and peptide dynamics, combustion diagnostics, stopped-flow technology and microfluidics, heterogeneous catalysis, vibrational circular dichroism, and high-resolution spectroscopy. These are exciting times for users of the dual-comb technique, as research has barely started to unlock its potential.
Who should attend:
Engineers, designers, and R&D scientists who are interested in utilizing QCL dual-comb spectroscopy. Those who want to further their knowledge on fast, high-resolution spectrometers, who work in fields such as test & measurement, medicine, optics, and imaging.
About the presenter:
Andreas Hugi, Ph.D., is the co-founder of IRsweep. He received his doctorate in single-mode and comb operation of broadband QCLs in 2013 under the supervision of Jérôme Faist. At that time, he was heading the development of external-cavity QCL development. After successfully demonstrating the first room-temperature QCL frequency comb in 2012, his research pivoted accordingly. At IRsweep, he is managing director and chairman of the board. In these roles, Hugi has continued to be a key player in the development of QCL frequency combs. His mission is to bring the technology to the market and conquer real-world applications. Hugi, among others, was awarded the ETH Medal for an outstanding doctoral thesis and the Omega student award for his master's thesis.
