Název v původním jazyce

Tunable diode laser absorption spectroscopy on 2.05 ?m for the CO2 concentration measurement

Popis výsledku v původním jazyce

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.
