Abstract

We report new FIR laser lines from ¹³CH₂F₂ molecule optically pumped by a waveguide CO₂ laser. The increased tunability (300 MHz) with respect to a conventional CO₂ laser allowed to pump ¹³CH₂F₂ vibrational transitions of large offset. 34 new laser lines have been discovered, ranging from 113.1 fim to 491.4 pm in wavelength, thus increasing the number of the known FIR laser lines from this important molecule to 99. The frequency of six new laser lines was also directly measured by heterodyne detection with already known laser lines.
