Process for generating laser beams in the 16 micron wavelengths range, particularly for U235-isotope separation, using a first CO2 gas laser (L1), whose CO2 molecules are raised to the (00 DEG 1) energy level by the supply of pump energy, and using a high-intensity radiation source, radiating into the laser tube, in particular a second C02 laser (L2), used as an injection laser, with the transition (00 DEG 1) -> (02 DEG 0), for occupying the upper laser level for the 16 micron radiation of the first laser (L1), which is to be stimulated, on the flexural vibration transition (02 DEG 0) -> (01<1>0). The laser pumping process of the first, chilled laser (L1) is carried out by means of electrical high-energy gas discharge in accordance with the TEA principle (transversly excited athmospheric pressure laser). The emission line of the injection laser (L2) is tuned in a range which covers the precise transition (00 DEG 1) -> (02 DEG 0) on a rotation level of the (02 DEG 0) level as well as of a virtual level (02 DEG 0)' at a freely variable distance from the line centre of the precise transition. The injection laser pulses, detuned in this way, are coupled into the 16 micron resonator of the first laser (L1), so that, on transition to the lower (01<1>0) laser level, its CO2 molecules emit quanta, the wavelengths of which are displaced by the magnitude of the detuning of the actual transition (02 DEG 0) -> (01<1>0). <IMAGE> |
