Tunable diode laser absorption spectroscopy on 2.05 ?m for the CO2 concentration measurement
Original language description
An experimental setup for the CO2 concentration measurement operating at 2.05 ?m in pulsed mode and its characterization are presented. The system consists of a light source, which is a tunable laser diode operating in pulse mode. The initial radiation from the diode laser is divided into two parts: the first part of the beam is directed to a retro reflector, and the second part is used for diode output power monitoring. The receiving system consists of a focusing optic and a photodiode. The absorptionis determined by comparing the intensities of the detected light on wavelengths absorbed and not absorbed by CO2 molecules. The prospects of the system change to a differential absorption lidar (DIAL) with a parametric generator as a light source that increases precision and range of generated wavelengths up to 10 ?m are outlined.
