NEW FIR LASER LINES AND FREQUENCY MEASUREMENTS FOR OPTICALLY PUMPED CD3OH

Twenty new cw FIR laser lines in CD//3OH, optically pumped by a CO//2 laser, are reported. The frequencies of 39 of the stronger laser lines were measured relative to stabilized CO//2 lasers with a fractional uncertainty, as determined by the reproducibility of the FIR frequency itself, of 2 parts in 10**7. Polarizations of the lines relative to the linearly-polarized CO//2 pump laser were measured with an external metal-mesh polarizer. Relative powers of the lines were determined by monitoring the laser output with a diamond window Golay cell with a 0. 24-mm-thick crystal-quartz filter to block the CO//2 radiation.
