Abstract :
The authors report the design and characteristics of a mid-infrared quantum cascade laser-based CO detection system using the absorption in the P (14) line, at 2086.32 cm−1. Measurements are performed through line scanning and signal processing to give sensitivities down to 2 ppm with the response time of 7 s.
