Ecc. Vasconcellos et al., NEW FAR-INFRARED HYDRAZINE LASER LINES AND THEIR FREQUENCIES, Journal of the Optical Society of America. B, Optical physics, 12(7), 1995, pp. 1334-1337
We have discovered 74 far-infrared laser lines pumped by regular and s
equence lines of a cw CO2 laser. The wavelengths range from 49.2 to 70
8.3 mu m. These new lines are to our knowledge the shortest-wavelength
far-infrared lines yet observed lasing in hydrazine. Frequency, pump
offset, and relative polarization were measured for most of these new
lines.
