The authors have measured 12 far-infrared laser frequencies of optically pumped CH{sub 3}OH, 6 of which are new lines. The frequencies range from 2.8 to 11.4 THz, with ten lines having frequencies higher than 7 THz. Two frequency stabilized CO{sub 2} lasers were used as standards for the heterodyne measurements. The frequency of the 26.4 {mu}m line at 11.4 THz is the highest ever measured with this technique. The lines were generated in a high-frequency far-infrared Fabry-Perot laser cavity pumped by a CO{sub 2} laser. The cavity has a high Q for wavelengths below 150 {mu}m, and uses variable coupling to optimize the cavity for each line.
