TE CS2 laser on the transitions of the 0001-0200 band

A widely used TEA CO₂ laser system with UV preionization has been essentially modernized to obtain the CS₂ molecule lasing. The output energy of 3 mJ on the transitions of the 00⁰1-02⁰0 band of CS₂ molecule (wavelengths of lasing is about 14 microns) has been experimentally achieved. For the interpretation of experimental results and definition of the maximum power performances the numerical modeling has been carried out. The system of the balanced equations for densities of population of bottom vibrational levels of CS₂ molecule and the first excited vibrational level of N₂ molecule was solved. The calculations showed that for the selective cavity the lasing on a number of the other transitions of CS₂, for example 00⁰1-10⁰0 (11.4 microns), 00⁰1-01¹0 (38 microns), 00⁰1-20⁰0 (45.5 microns), 00⁰1-12⁰0 (117 microns) is possible also.
