Abstract

The development of a field-portable, cryo-cooled infrared tunable laser absorption spectrometer (TLAS) will be presented. The configuration includes either multi-quantum-cascade or multi-lead-salt lasers, a 36 m Herriott-cell with integrated laser/detector with cooling via Stirling cryo-coolers.
