The methanol isotopomers have been systematically investigated as a source of far-infrared (FIR) laser emission utilizing a newly designed optically pumped FIR-laser system. The system combines several different FIR laser cavity designs with the extended line coverage available from an efficient CO{sub 2} laser. Many new FIR laser lines have been observed, pumped by high-J-fundamental, sequence, and hot-band CO{sub 2} transitions. The observed new FIR laser lines cover a broad spectral region, and contribute significantly to the frequency coverage of the optically pumped FIR laser. Many new short-wavelength FIR laser transitions for normal methanol have been observed using a 2-m-long FIR laser cavity. In addition, acetaldehyde molecule has been reinvestigated as a source of FIR laser media. Accurate heterodyne frequency and CO{sub 2}-laser pump frequency offset measurements have been made for most of new FIR laser lines.
