Effect of helium addition on output power of a CW optically pumped far infrared methanol laser

Abstract The results of an experimental study of the effect of He addition as a buffer gas on the output power of a CW optically pumped methanol FIR laser are presented. Results of the measurements are compared with results of calculations executed on the basis of the theoretical model proposed earlier [J.S. Bakos, Preprint KFKI-1990-171D, Hungarian Academy of Science (1990) ], and that of the results of gain and line broadening measurements [J.S. Bakos, T. Karpati and Z. Sorlei, Int. J. Infrared Millimeter Waves 6 , 867 (1985)], and good agreement is found.
