New CW FIR laser lines obtained in ammonia pumped by a CO2 laser, using the Stark tuning method
Abstract
We report fifty seven CW FIR emissions observed in NH3, by resonant pumping with a CO2 laser. Exact coincidences between IR absorption lines of the gas and emission lines of the CO2 laser have been carried out by Stark tuning. IR frequency shifts, up to 30 GHz, have allowed the pumping of forty three NH3 transitions. These FIR emissions correspond to thirty one different wavelengths in the 50 400 μm range; eighteen ones of them are new emitted wavelengths by pumping with the CO2 laser.
