Abstract
Direct measurements of small signal and saturated gain in cw laser pumped CH3OD are reported for three lasing transitions of 57 μm, 82 μm and 103 μm. The 57 μm transition has a measured gain of 0.6/m, the strongest gain in methanol reported so far. Moreover small gain saturation of this line makes it to be one of the strongest known cw FIR laser lines.
