We have discovered 74 far-infrared laser lines pumped by regular and sequence lines of a cw CO2 laser. The wavelengths range from 49.2 to 708.3 μm. 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.
