Possible stabilization of the frequency of a CO2 laser using an external Stark cell containing 1-1 difluoroethane

Results are presented of measurements of the Stark modulation index and absorption coefficient of CO₂ laser radiation due to the P(24) line by 1-1 difiuorethane (C₂H₄F₂₎. The possibility of stabilizing the CO₂ laser frequency using a Stark cell is demonstrated and the laser frequency tuning efficiency within the P(24) line of the 00^o1–10^o0 transition is determined.
