Abstract
In an optically pumped far-infrared (FIR) laser the molecular gas is excited from its ground vibrational state to a higher vibrational state by an external laser source (usually a CO2 laser). Population inversion is obtained between two rotational levels within the excited vibrational state. The laser cycle is closed by the relaxation of molecules from the excited vibrational state to the ground state .
