A compact CO{sub 2}-{sup 13}CH{sub 3}F laser system where the FIR laser cavity is inserted in a pump, three-monitor CO{sub 2} laser cavity, with optically-switched semiconductor cavity-dumping, will be designed and tested. The 1.207 mm cavity-dumped oscillator is expected to be characterized by predominantly single longitudinal mode, narrow linewidth operation and to produce peak power of order 100 kW in pulses of order 10 ns duration. The 1.2 mm wavelength lies in an atmospheric transmission window (1 dB/km at sea level), which opens up the possibility of millimeter-wave space- of ground-based radar and communications systems. The laser can also be used as a FIR spectroscopic source to investigate dynamic properties of elementary excitations of the solid state. 10 refs., 7 figs.
