Abstract
A new short-wavelength far-infrared $laser^{a}$ is used to generate optically pumped far-infrared laser radiation in the wavelength range 30 to $150 \mu m$ in methanol. The large-amplitude torsional motion in methanol accounts for its rich far-infrared spectra. Its infrared absorption bands overlap well with the $CO_{2}$ laser providing for the generation of strong high-frequency laser lines in the far-infrared. Methanol is an excellent short wavelength laser medium and about 40\% of its lines have wavelengths shorter than $150 \mu m$. We have already obtained a four-fold increase in the number of laser lines in the $50 \mu m$ region, and are now pushing to increase the density of laser lines with $\lambda < 50 \mu m$. A list of the strong laser lines observed in methanol, in the range 30 to $150 \mu m$, will be presented in this work.
