Towards broadband mid-infrared trace gas sensing using a supercontinuum source

Abstract

Recent advancement of mid-infrared supercontinuum (SC) light sources has open up new possibilities in laser-based trace gas sensing, supporting the detection of multiple gas species in parallel. In this contribution, I will present our most recent development of a fully integrated SC-based trace gas sensor featuring sub-ppm sensitivity. Field application involving simultaneous detection of up to seven species for quality control of stored fruits will be demonstrated. A novel upconversion-based detection method will also be briefly covered, highlighting the advantages of SC sources for future trace gas sensing research.

Biography

Qing Pan obtained his PhD in 2016 from the University of Twente, where he studied time-resolved molecular photodynamics using femtosecond supercontinuum pulses. Afterwards he joined the trace gas research group at Radboud University in Nijmgen. His research currently focuses on the development of mid-infrared supercontinuum-based trace gas sensors.
