In a discharge-pumped F2 laser, it is known that the major mechanisms for formation of the population density of the laser upper level (F2∗ (D′)) are the neutral channel and the ion channel reactions. In order to study the degree of contribution of the neutral channel or the ion channel reactions, the population densities of the fundamental species, such as the excited F and He atoms and a F− ion and an electron, have been measured by means of the optical interferometric and absorption methods. On the basis of these experimental results, the population density of the laser upper level is estimated with the aid of simple rate equations, and the formation processes of laser upper level molecules have been discussed.
