A sulfur dioxide detection platform based on photoacoustic spectroscopy and a 266.22 nm high-power stabilized LD-pumped solid-state Q-switched laser

A sulfur dioxide detection platform based on photoacoustic spectroscopy and a 266.22 nm high-power stabilized LD-pumped solid-state Q-switched laser

A ppb-level sulfur dioxide (SO2) monitoring platform was developed by exploiting standard photoacoustic spectroscopy and a novel, highly stable UV laser. A 266.22 nm LD-pumped solid-state, acousto-optic modulator Q-switched laser with high beam quality (M2 =1.0275) and excellent output optical power...
