Paper Abstract

The discovery of line-tunable cw NH3 lasers has led to new sources of powerful coherent radiation in the 11 to 14 μm region. In this paper we describe recent progress in the development of these lasers, and present results obtained with a variety of laser devices. Compact line-tunable cw NH3 lasers have operated with pump powers of less than 1 W from conventional CO2 lasers, while larger devices give output powers as high as 5.5 W with conversion efficiencies of 33%. on more than 80 different NH3 transitions has been obtained by pumping both 14NH3 and 5NH3. The frequencies of many of these transitions have been accurately measured by heterodyne spectroscopy.
