Mid-infrared photoacoustic gas monitoring driven by a gas-filled hollow-core fiber laser

Abstract Development of novel mid-infrared (MIR) lasers could ultimately boost emerging detection technologies towards innovative spectroscopic and imaging solutions. Photoacoustic (PA) modality has been heralded for years as one of the most powerful detection tools enabling high signal-to-noise rat...
