Abstract:
A theoretical analysis is made of existing experimental data on the stimulated emission spectrum of an optically pumped CF4 laser. It is found that weak transitions with changes in the rotational angular momentum (ΔR=±1, ±2) play an important part in the excitation and emission of the CF4 molecule. A model is proposed for the operation of a CF4 laser based on the concept of coupled transitions and explaining the negligible role of rotational relaxation in the formation of the laser stimulated emission spectrum.
