We are thrilled to announce that Dr. Ibrahim Sadiek, will be presenting an invited talk on ‘Precision Frequency Comb Spectroscopy of Reactive Molecular Plasmas‘ at the ‘S&I 13: Active Optical Sensing; during CLEO 2024’.

If you are joining CLEO, join us in exploring how optical frequency comb spectroscopy can help understand the intricate chemistry of non-thermal molecular plasmas.

Two Species–One Wavelength Method Defeats Cross-Sensitivity. This article tackles cross-sensitivity challenges in species concentration detection, a common hurdle in many sensor technologies.

We present a proof-of-principle study to overcome cross-sensitivity by taking advantage of the distinct optical saturation characteristics of different gas mixture components. By controlling the absorption contribution of a selected species by intentional optical saturation, simultaneous and quantitative detection of two interfering species becomes possible even without the need for spectral scanning.

Demonstrated with direct absorption and cavity-ringdown setups, the method offers a new opportunity to further enhance laser-based analyzers for complex gas mixture analysis in environmental and other applications.

2nd “Carbon Recycling Energy Research CenteRecently (CRERC)” International Seminar.

Dr. Ibrahim Sadiek delivered an exclusive presentation at the 2nd Carbon Recycling Energy Research Center (CRERC) International Seminar, held at Ibaraki University in Japan. He showcased the power of absorption spectroscopy with frequency comb lasers, emphasizing their wide bandwidth and exceptional spectral resolution for diagnosing non-thermal quantum states in plasma-generated chemical species.

The seminar sparked discussions on using frequency combs for simultaneous measurements of multiple chemical species in CRERC’s combustion chambers.

Mid-infrared frequency comb spectroscopy shines the way to dynamic process control of plasma nitriding.

In a collaboration between experts from the Leibniz Institute for Plasma Science and Technology (INP), neoplas control, RÜBIG, and Menlo Systems, we’ve achieved a remarkable milestone. Together, we successfuly developed and applied frequency comb-based VIPA (Virtually Imaged Phased Array) diagnostics for precise measurements in plasma nitriding, even under challenging industrial conditions.

Our achievement recently earned recognition in an an article published in Laser Focus World. Stay tuned for further advancements in this dynamic field!

Dr. Ibrahim Sadiek has received the prestigious “Faculty Prize” for the best PhD thesis from the Faculty of Mathematics and Natural Sciences, Kiel University, Germany.

Dr. Sadiek’s thesis brilliantly bridges spectrometer development, high-resolution spectroscopy, and trace gas detection. Notably, his work introduces an innovative detection scheme for trace gases, with the potential to enhance absorption-based spectrometers significantly.

This achievement was made possible through support from the HOSST program and Kiel’s “Future Ocean” cluster of excellence, both dedicated to interdisciplinary marine sciences research.
