In this paper, infrared (IR) and far-infrared (FIR) laser emissions from a TE CO 2 laser pumped NH 3 gas are reported. 8 IR laser emissions near the wavelength of 12 μm were observed by using 4 different CO 2 laser lines for the pumping. 3 IR laser emissions in P-branch of vibrational-rotational band (ν 2 → G) oscillated simultaneously in two pumping cases, i.e. pumping with the R(30) or R(16) line of 9.4 μm band from the CO 2 laser. 26 FIR laser emissions (26.45 μm ∼ 281.0 μm) were observed by using 12 different CO 2 laser lines, and the 10 FIR emissions of them may be new laser emissions as far as we know.
