The optically pumped FIR laser lines at 119 μm from CH3OH and at 127 μm from13CD3OH are known to be the most powerful in the far infrared spectral region. We report on efficiency measurements for our waveguide laser system. The effect of various parameters was investigated, resulting in the highest efficiency ever reported for the 119 μm line. The Stark effect and others parameters of the 127 μm were measured, and a new13CD3OH laser line at 175 μm discovered, with the same pump transition. These measurements are helpful for completing the assignment already proposed for the 127 μm line.
