The authors report 18 new laser lines from {sup 13}CH{sub 3}OH generated in an optically pumped far-infrared laser; the laser lines are in the range of 54.2--420 {micro}m and are all characterized in wavelength, polarization relative to the pumping CO{sub 2} radiation, and pump offset relative to the CO{sub 2} center frequency. The frequencies of seven of these new lines along with 10 previously reported lines were measured by an accurate heterodyne technique, mixing them in a metal-insulator-metal (MIM) point contact diode, with another laser line of known frequency.
