QCLs for the measurement of gases

In the area of gas sensing we work on novel photo-acoustic detection schemes including quartz enhanced photo-acoustic (QEPAS), stand-off open-path measurements using a portable QCL system and multipath Herriot cells for improved sensitivities. Detection limits in the low ppb range have been reached already (e.g. SO2 by QEPAS)
