We report the identification and characterization of eight new FIR laser lines from methanol (CH 3 OH) in the range 48.4 to 453.7 m pumped by sequence and hot bands of a cw CO 2 laser. Frequency measurements for most of the new FIR laser lines and from previously reported ones were obtained in the r

โฆ Synopsis
We have revisited the assignments of the far-infrared laser lines emitted by 13 CH 3 OH by comparing the laser systems to a high resolution Fourier transform absorption spectrum of 13 CH 3 OH. The absorption spectrum was analyzed by means of the ''Ritz'' program, which calculates the energy level values directly from the Rydberg-Ritz combination principle. We report new assignments for 11 FIR laser transitions, 17 frequency predictions for new possible laser lines, and we confirm 11 previous assignments.

Progress in the analysis of the infrared spectrum of CH 3 OH in the 930 -1450 cm ฯช1 region has led to assignments, confirmations, or new insights for a number of far-infrared laser (FIRL) transition systems optically pumped by CO 2 lasers. Many of the systems involve FIRL transitions among the CO-st
We report the Stark behavior of 31 FIR laser lines of CH 3 18 OH optically pumped by a CO 2 waveguide laser. We observe various behaviors for different laser lines: power decrease, power enhancement, shifting and splitting of the laser lines, or no effect at all. Since the observed Stark line shapes
Sub-Doppler signals from the gain curves of four lines of a transversely pumped far-infrared methanol laser were used to stabilize the frequencies of the laser. The frequencies of four of the strongest FIR laser lines (70, 119, 123, and 570 m) were measured. Lasers locked to these lines have a frequ
We have investigated the high-resolution Fourier transform spectrum of the C -O stretching fundamental band of CD 3 OH in order to assign far-infrared ( FIR) laser transitions. The absorption spectrum was analyzed by means of the ''Ritz'' program, which calculates the energy level values directly fr
