Abstract

The influence of laser action on the change of the vibrational temperature T_ν of the asymmetric stretch mode of CO₂ in the discharge of an electrically excited CO₂ laser is investigated, employing a periodically switched laser. The vibrational temperature change ΔT_ν is calculated from the measured excess of vibrational energy stored in a nonlasing discharge as compared to that in the gas under lasing conditions. Results are presented for ΔT_ν as a function of T_ν for different values of discharge currents. The gas compositions were CO₂Single Bond signHe and CO₂Single Bond signHeSingle Bond signN₂.
