Abstract :
In an optically pumped sub-millimeter wave laser (OPSMMWL) system, the infrared (IR) pumping laser with collision broadening which was closer to the practice was considered. A more precise mathematical model was set up. When the IR pumping laser line had the Lorentz function structure, by solving the semi-classic density matrix equations, the generalized form of SMMW signal gain Gs and IR pumping signal absorption coefficient Gp were obtained.
