Dual gas (NH3and NO2) laser absorption measurement by tailored signal and idler wavelength in difference frequency mixing process


Absorption measurements of NH3in 1.53 μm wavelength region and NOx in 3.46 μm wavelength region are performed at the same instant by using single optical gas sensing system based on difference frequency generation (DFG).
