We report new far-infrared laser lines generated from two fully deuterated isotopomers of methanol: ¹²CD₃OD and ¹³CD₃OD; five from ¹²CD₃OD and 22 from ¹³CD₃OD, which added to the previously reported far-infrared laser lines in these two molecules sums up to 300. The laser lines were mainly pumped by the 10R (regular) and 10SR (sequence) bands of a cw - CO₂ laser. We measured their frequencies, relative intensities, relative polarizations and pump offsets. The laser lines are in the spectral range from 43.697 to 719.426 µm (6 860 664.6 to 416 710.4 MHz).
