Influence of impurities of high-molecular compounds on the temperature of the gaseous medium in a CO2 laser

An experimental investigation was made of the influence of high-molecular compounds on the temperature of the gaseous medium and on the output power of a CO₂ laser. The temperature of the gaseous medium decreased on introduction of small amounts (~5%) of SnCl₄, CCl₄, Fe(CO)₅, and MoF₆ impurities. The rate constants of deactivation of the 001 CO₂ level were determined for mixtures to which various high-molecular compounds were added. It was established that a resonant interaction of MoF₆, SnCl₄, and other molecules with the 010 level of CO₂ influenced the output power of the investigated CO₂ laser.
