We report 16 new far-infrared (FIR) laser emissions of CD2Cl2 These lines are obtained by optically pumping the active molecule by means of a large-tunability waveguide CO2 laser. Our tunability of 290 MHz around each CO2 laser emission allows fur the excitation of large-offset absorption transitions of CD2Cl2, not reachable by conventional CO2 lasers. While the overwhelming majority of the known FIR laser emissions of CD2Cl2 are polarized parallel to the polarization of the pump CO2 line, 13 of the 16 new lines reported in this paper are polarized perpendicularly to the corresponding CO2 pump line. The presence of both perpendicular and parallel lines is extremely important for the assignment of laser transitions.
