Comparison of low-pressure DC glow discharge and dielectric barrier discharge in CO2-laser mixture by optical emission spectroscopy

Original language description

Nowadays the CO2 lasers are used in many technologies, including medicine and material processing industry. Besides original low-pressure low-power lasers pumped by DC glow discharge, the attention is focused on the high power atmospheric pressure lasers. We use optical emission spectroscopy to study both low pressure (from 266 Pa to 1330 Pa) DC glow discharge (DC GD) and the dielectric barrier discharge (DBD) (from 5 kPa to 100 kPa) in mixtures of helium, nitrogen and carbon dioxide used in CO2 lasers.Considering the emission spectrum of the discharges mentioned above, we can find bands of the first and the second positive systems of the nitrogen molecule. From these bands it is possible to deduce energetic balance and the vibrational temperature [1]. In our contribution, the vibrational temperature of nitrogen is determined by means of optical emission spectroscopy from the second positive system band of the nitrogen molecule for various discharge currents in DC glow discharge and f
