Effect of organic additives on the upper laser level relaxation rate and the gain of a TE CO2 laser

The vibrational relaxation rate of the upper laser level (0001) in the presence of xylene and tripropylamine is determined by experimental investigation of the time behaviour of the gain. It is shown that the presence of such additives in amounts which are optimal for TE CO2 lasers has no influence on the vibrational relaxation rate of the 0001 level. The increase in the electron excitation rate is found by experiment to be about 17% and 30% for xylene and tripropylamine, respectively. At the same time the duration of the excitation current pulses decreases considerably. Calculations show that the additives reduce the values of the 0001 level population and the gain, in a good agreement with the experimental results.
