Spectroscopy of optically pumped ammonia and deuterium oxide near 1 THz
Original language description
Molecular gases like ammonia (NH3) and deuterium oxide (D2O) can be used as active media for optically pumped terahertz lasers (OPTL). In this paper we present spectroscopic measurement of chosen NH3 and D2O lasing lines near 1 THz. Rotational-vibrational transitions are pumped by mid infrared quantum cascade laser (MIR QCL) which offers more precise tunability in MIR spectral range than standard optical pumping methods (CO2, N2O lasers). This allows to access new lasing lines. Frequency domain measurements of NH3 and D2O under different pressure, pumping frequency and pumping power are performed. The results show high gain obtained for NH3 (3,3) line at 1.073 THz and very low gain for D2O (4,3,2) line at 533 GHz due to the low population. © 2017 IEEE.
