Hydrazine (N2H4) and the deuterated isotopes of difluoromethane (CD2F2) and methanol (CH3OD and CD3OH) have been reinvestigated as sources of far-infrared (FIR) laser emissions using an optically pumped molecular laser system designed for wavelengths below 150 microns. With this system, seven FIR laser emissions from optically pumped N2H4, CH3OD and CD3OH were discovered with wavelengths ranging from 54.0 to 185.0 {/content/CPP0L1JC2E41U5F2/xxlarge956.gif}m. In addition, the polarizations of eight previously observed laser emissions from optically pumped N2H4, CH3OD and CD2F2 were measured for the first time. All laser emissions are reported with their operating pressures, relative polarizations and wavelengths, measured to c0.5 {/content/CPP0L1JC2E41U5F2/xxlarge956.gif}m. The effectiveness of this particular system in generating short-wavelength laser emissions has been further demonstrated by the improvement in output power observed from nine known FIR laser emissions.
