| 摘要 |
The disclosure relates to a pulsed gas laser comprising an optical resonant cavity, a CO2 lasing medium, structure for containing the CO2 lasing medium within the optical cavity and a device for causing a population inversion in the lasing medium, with a novel improvement comprising structure for causing a laser pulse comprising a wavelength in the near 14 mu m and near 16 mu m range. The structure for cooling the CO2 lasing medium to less than about -40 DEG C as well is a structure for pumping the maximum inversion of CO2 molecules within the lasing medium by minimizing the population in the 010 level.
