Short-wavelength far-infrared laser cavity yielding new laser emissions in CD3OH

A significantly improved far-infrared laser has been used to generate optically pumped laser emissions from 26 to 150 mum for CD3OH. Using an X-V-pumping geometry, several new laser emissions have been found for CD3OH. In addition, an increase in power, by factors from 10 to 1000, fur many of the previously known shorter-wavelength laser lines, below 100 mum, has been observed. Frequency measurements fur several lines have also been performed and have been reported to a fractional uncertainty up to +/-2 x 10(-7), permitting the spectroscopic assignment of the laser transition. One of the frequency-measured lines, 44.256 mum observed using the 10R34 pump, has confirmed the assignment of the previously reported FIR emission (n, K; J) = (1,7; 20) --> (0, 8; 20)A in the ground vibrational state.
