Abstract :
We report low threshold Raman and hyper-Raman far-infrared laser emission associated with the14NH3 , 
infrared transition. Using a circular metallic waveguide FIR resonator, which also acts as a microwave resonator, threshold pump powers were 50 W CO2 -laser radiation and 150 W CO2 , 15 W microwave for Raman and hyper-Raman emission, respectively. The hyper-Raman process is suitable to generate frequency-tunable FIR radiation.
