Abstract

We present an all-fiber laser gas analyzer using quartz-enhanced photoacoustic spectroscopy, featuring a dielectric-coated side-polished fiber, custom quartz tuning fork, and acoustic micro-resonators, achieving over 42 times enhancement in QEPAS signal for improved detection performance.
