Far-infrared (FIR) lasers are frequently used in plasma diagnostics, molecular spectroscopy, and solid state material testing. The conversion of the power of the pumping laser into the FIR laser so far is usually not as effective as that theoretically predicted, because of the bottleneck'' of the vibrational relaxation rate. It is therefore worth investigating the relaxation rates of the excited laser material with added buffer gases, which may influence the speed of deexcitation processes, looking for the proper materials to help to achieve more effective laser operation. Here, double-resonance infrared to far-infrared spectroscopic measuring system with tunable far-infrared lasers and frequency stabilized CO[sub 2] pumping lasers was constructed and used to investigate relaxation mechanisms in far-infrared laser material and also in the presence of added buffer gases.
