Frequency-selective stimulated emission from CO₂molecules in the 16 μ band

CO2 laser oscillating in the range of 16 μm

“…It was noted [14] that line R11e of CO 2 transition 02 0 0-01 1 0 fell in the red tail of the 238 UF 6 absorption peak. Therefore, it was assumed in the calculations that oscillation in channel 2 occurred in line R11e.…”

“…Qualitative trends in the behavior of I i m and E i , which can be used to attain the maximum value of one parameter or another, were found. It was noted [14] that a peak power I 2 m ~ 0.5 MW/cm 2 is suggested to be sufficient for separating U isotopes. Figures 2-4 show that the value obtained from the calculations approaches this value under optimum conditions.…”

“…It was shown experimentally and theoretically that oscillation of a CO 2 laser in the range of 16 (14) μm is possible at room temperature. The instance where oscillation resulting from a pulsed electric discharge begins to develop in channel 00 16 (14) μm.…”

“…Oscillating waves were separated along mutually orthogonal polarizations in order to create a two-wave mode in a single volume of active medium. A radiation pulse of wavelength 16 (14) μm was emitted near the intensity maximum of the laser pulse in channel 00 0 1-02 0 1(10 0 0). Its duration at the base was significantly less than that of the dumping pulse.…”
