Abstract :
The optimization of the active medium and its electrical discharge pumping conditions based on the original technique of gain measurements on the several bands (0001-1000, 0002-1001, 0111-1110) of CO2 molecule allowed to obtain in the simple TE CO2 laser with UV preionization (the active media length is 70 cm, the width of electrodes is 2.5 cm, the interval between electrodes is 2 cm, the voltage on the 0.2 microFarad capacitor is 6.5 kV) the powerful lasing (57 mJ) on the 0200(1000)-0110 band (lambda~l16 (14) micrometers) at room temperature.. To increase the power performances of the 16 (14) microns CO2 laser the possibility of lasing on the 0201-0111 band have been experimentally and theoretically investigated under the combined (electrical + optical) excitation of the active medium. The necessary conditions for the effective lasing have been determined. It is shown that in optimum conditions the output energy can reach 1,3 J/l at the peak power 5 MW and at the full efficiency of 2%.
