An Optically-Pumped Frequency Stable Tunable Maser and Infrared-Microwave Double-Resonance Experiments in Ammonia
Abstract
dc:descriptionMicrowave emission attributed to a linear cascade effect has been observed from ('14)NH(,3) optically pumped by a CO(,2) laser. The emission is tunable over the saturated homogeneous linewidth of the ground state sQ(5,4) inversion transition at 22.653 GHz. The circulating power density of the optically pumped emission is 0.54 watts/cm('2) at NH(,3) pressure of 0.91 torr and CO(,2) R(6)(,10) laser pulse energy of 60 mJ. The cell design and frequency characteristics are presented as an Appendix.
