The

OH isotopic form of methanol has been investigated as a far-infrared laser medium for wavelengths above 100 μm using a recently constructed optically pumped molecular laser system. This system, which utilizes a transverse pumping geometry of the far-infrared laser medium, has generated 43 new far-infrared laser emissions ranging in wavelength from 106.4 to 700.3 μm. Along with the wavelength, each laser emission is reported with its optimal operating pressure, polarization with respect to the CO2 pump laser, and relative intensity.
