An Experimental and Theoretical Investigation of CO-QEPAS Sensor Based on a High Power DFB Diode Laser

A high sensitive CO-QEPAS sensor with a high power 2.33 μm diode laser was demonstrated. A 11.2 ppm detection limit was obtained and the pressure and temperature sensitivities of the reported sensor were analyzed.
