✦ Synopsis

We report new FIR laser lines from 13CH2F2 molecules optically pumped by a waveguide CO2 laser. The increased tunability (300 MHz) with respect to a conventional CO2 laser allows the pumping of a 3CH2F2 vibrational transitions of large offset. 34 new laser lines have been discovered, ranging from 113.1 gm to 491.4 gm in wavelength, thus increasing the number of known FIR laser lines from this important molecule to 99. For all the new lines and many (36) of those known previously, precise offset measurements through the transferred Lamb-dip technique were performed. The frequency of six new laser lines was also directly measured by heterodyne detection with known laser lines.
