The operating parameters of small optically pumped FIR lasers at relatively high pressures have been investigated. In these studies typical dimensions for the Far Infrared Laser are 2mm in radius by 5cm in length. For the $1.2\mu 13CH3F$ laser, pressures to a few Torr were used. It is shown that in these lasers the maximum pressure for oscillation is a strong function of $CO2$ laser pump power. These results will be compared with the parameters derived from our earlier studies of rotational and vibrational collisional processes in $\mathrm{<mrow\; data-mjx-texclass="ORD">13</mrow>}CH3F.12CH3F$ and $CH3OH$ have also been studied.
