Laser-pumped molecular laser

The parameters of laser-pumped molecular lasers are investigated. It is established that the energy and tuning characteristics of an NH₃ laser (E_g = 1.5 J, efficiency 20%, P_av = 20 W, radiation frequency tuning band 753–890 cm^-1) are decisively influenced by the addition of N₂. A focusing raster optical-pumping system has made it possible to obtain a specific lasing energy 12 J/liter. A CF₄ laser with lasing energy 40 mJ operates in the 612–655 cm^-1 band. Experiments on dissociation of the molecules CCl₄ and UF₆ were carried out with the aid of NH₃ and CF₄ lasers. The systems and methods of producing Raman lasers (RL) are presented. An effective RL amplifier on rotational transitions in compressed H₂, which transforms tens of beams of Nd lasers into one coherent beam of the first Stokes component with λ ? 1.13 μm at an efficiencyup to 70%, is described.
