For obtaining powerful THz emission of radiation we offered to use CS/sub 2/ molecules pumping in the 10/sup 0/0-00/sup 0/1 channel by the radiation of TEA CO/sub 2/ laser working on lines of the 01/sup 1/1-11/sup 1/0 hot band (/spl lambda//spl sim/11.4 /spl mu/m). In this case THz radiation can take place in the 00/sup 0/1-12/sup 0/0 channel of CS/sub 2/ molecules (/spl lambda//spl sim/117 /spl mu/m). Our calculations show that for the pressure of the active medium /spl sim/0.1 atm (L/spl sim/1 m, V/spl ap/0.1 liter) and pumping energy 1 J output energy can achieve some tens mJ and the peak power >0.1 MW. The efficiency of transformation of the energy pumping into THz radiation can reach several percents.
