Characteristic features of the dissociation of UF₆molecules in the radiation field of a pulse-periodic CF₄laser

Generation of 16 Micrometer IR Laser by theOptical Pumping of CF4 Gas Molecules

“…The performance of the CF4 laser has been investigated in terms of the pumping energy of the TEA CO2 laser, where the threshold pumping energy was found at a CF4 gas pressure of 7mbar and temperature of 150 Kº, figure (4). A significant energy fluctuation was noticed from pulse to pulse.This unstable behavior resulted from the action of the TEA CO2 laser in many longitudinal and transverse modes, and as the output of a normal multimode CO2 laser varies erratically in frequency range of 1-2 GHz around the pump laser line center,several of the close lying CF4 absorption transitions can be pumped simultaneously.The output from the CF4 laser contained the remainder of the pumping CO2 laser radiation (1073cm ֿ¹).Although it is a difficult to separate the output wavelength from the pumping wavelength without special filters, the monochromator dispersive element itself is used in our experiment to separate them but with great losses in the detected CF4 output energy.…”

“…There are now many optically pumped molecular lasers (OPML's) in which pumping are accomplished by a TEA CO2 laser. The performance of these roto-vibrational molecular lasers at low temperature can be greatly improved [1,2].Such improvements are particularly important in view of the potential applications of these lasers in a variety of photochemical processes based on selective vibrational excitation of molecules [3,4].…”
