Abstract
The characteristics of NH3 laser pumped by a TE CO2 laser pumped NH3 laser is discussed. 38 IR laser lines in the wavelength region from 10.7 to 13.3μm wser observed by CO2, 9R (30) line. The emission intensity of each line depended on both the temperature of the NH3 laser tube and the ratio of NH3 to N2. Most of the laser lines could, however, be observed under a same condition. 12.280μm line was observed for the pumping of CO2, 9R (30) and CO2, 10P (32) lines respectively. The slight frequency difference in both cases were discsuued. Furthermore, 12.078μm line, which was the strongest emission line in this experiment, was used to pump an InSb spin-flip Raman (SFR) laser, successfully.
