Abstract
The conditions of obtaining of synchronous generation on two far separated frequencies in range 9 - 13 μm by means of the NH3 - CO2 laser system are reviewed. It is shown, that the two-frequency generation can be achieved by three main ways: (1) using the features of diffraction gratings operating in an autocollimation of the high orders; (2) using the effect of saturation of active medium of the converter of NH3 - CO2 laser system; (3) using the raster system of optical pumping of the converter. The advantages and lacks of each way are reviewed at remote sensing of atmosphere in range 9 - 13 μm.
