Abstract

Until recently hydrazine had 35 known far-IR laser lines when optically pumped by a ¹²C¹⁶O₂ cw-laser. We have discovered 127 new lines pumped by regular, sequence, and hot band lines of a ¹²C¹⁶O₂ cw-laser. One hundred and one of these new lines have wavelengths less than 200 micrometers , the shortest wavelength line is 49.2 micrometers . Of the 162 known lines, 139 have been frequency measured. We list the pump line, pump offset, FIR wavelength and frequency, optimum pressure, relative intensity, and relative polarization for each line. Preliminary work has also identified 12 new lines when hydrazine is pumped by an N₂O laser.
