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