Abstract

Quartz enhanced photoacoustic spectroscopy (QEPAS) is a high performance trace gas detection technique that plays an important role in food safety, pollution monitoring and breath analysis applications. It is well known that the sensitivity of QEPAS gas detection system is proportional to excitation laser power and thus the performance of QEPAS-based sensors can benefit from the high output power levels achieved as a result of technology developments by the high power laser. This paper mainly introduces three kinds of QEPAS gas sensor based on fiber-ring laser.
