Relaxation Processes and Population Inversion in a Multicomponent Plasma in a Co2 Discharge Laseretail the population inversion mechanism in a CO. laser, we must recall some fundamental information on these molecules, consider some aspects of the theory of relaxation in a mixture of molecular gases, and present briefly the available information on the CO. laser action.宿醉 发表于 2025-3-23 15:00:01

Dissociation of Co2 Molecules in a Co2 Laser Gas-Discharge Plasmamedium in a CO. laser under the action of electrical discharges, to determine the nature of the influence of these changes on the properties of the active medium, and to review (on this basis) ideas on the physical processes resulting in population inversion.Accord 发表于 2025-3-23 23:58:34
Relaxation Processes and Population Inversion in a Multicomponent Plasma in a Co2 Discharge Laserma is a multicomponent mix-ture. This must be borne in mind in studies of the CO. laser action, i.e., in discussing the processes which ensure pumping of the upper laser level and the relaxation processes which depopulate the lower and upper laser levels.

Experimental Determination of Laser Level Populations. Vibrational Temperaturesults deduced from measurements of the laser gain . However, it is clear from Eqs. (2.9) and (2.10) that the direct results of such calculations are the vibrational temperatures of molecules in different normal modes and of the absolute populations of the corresponding vibrational levels.

Review of Literature on Electrical and Optical Properties of Plasmas in Molecular Discharges and Basn the CO2 molecule. Later investigations, which were largely empirical, resulted in improved output power and efficiency. This became possible mainly because of the addition of nitrogen, helium, water vapor, and xenon, and also because of the optimization of the resonator structure, A detailed revie连系 发表于 2025-3-24 14:36:49

In this method an electric probe, i.e., a small electrode of spherical, cylindrical, or planar shape, is introduced into a discharge and subjected to a potential lower o刺激 发表于 2025-3-24 15:54:39
Results of Investigations of Gas-Discharge Plasmas in Molecular Gasesgree of perturbation caused by a probe is governed by the ratio of the probe radius to the mean free path of electrons in the plasma a/λ.. The theory demands that this ratio be small and this imposes an upper limit to the range of pressures in which the probe method can be used. If we assume thIntrovert 发表于 2025-3-24 22:24:57
