Fluorescence A 4.3 μm en fonction de la pression dans un laser CO 2 supraatmospherique
Abstract
We have observed the 4.3 μm fluorescence signal produced by a superatmospheric double-discharge CO 2 laser, up to a pressure of 5 atm. The evolution of the signal amplitude with pressure reveals an unusual behaviour which we associate to the hot bands. Moreover, we have deduced the V-V relaxation times of CO 2 in mixtures CO 2:N 2:He of (10:5:85) and CO 2:He of (9:91).
