Abstract :
Using for the first time a waveguide CO2 laser with a tunability of 300 MHz, in order to pump large offset infrared absorptions, we obtained 34 new far-infrared laser lines from the hydrazine molecule; their wavelengths range from 155.2 to 669.3 μm. All of the new lines and some other already known laser emissions are characterized in the wavelength, the polarization relative to that of the pumping CO2 laser, the optimum pressure of operation, relative intensity, and the offset relative to the CO2 center frequency
