gasbanor SF6 Decomposition sensor module

A ppb-level photoacoustic multicomponent gas sensor system for sulfur hexafluoride (sf 6) decomposition detection was developed by the use of two near-infrared (NIR) diode lasers and an ultraviolet (UV) solid-state laser. A telecommunication fiber amplifier module was used to boost up the excitation optical power from the two NIR lasers.
