Physical and chemical processes in the working mixture of I2 laser of the UV-range with optical pumping

A creation of a laser with a wavelength in UV spectrum field, as an element of lidar systems, can be perspective for monitoring of the atmospheric impurities. A gas laser on electronic transition D'→A' (342 nm) with optical pumping (I 2 - laser) is based on collisional transfer of electronic energy between terms 3Σ u +(D) and 3 Π 2g (D') of iodine molecules. The dependence of intensity of luminescence D'→A' on pressure of buffer gas for 25 substances was studied. Effective working mixtures of I 2 -laser with optical pumping on a basis of perfluoroalkanes were found.
