Abstract

In this paper, an overview is presented on the frequency tunable methylfluoride Raman laser. By use of a continuously tunable high pressure CO₂ laser as pump source, tunable far-infrared radiation can be obtained from all the stable isotopes of methylfluoride which have symmetric top structure. Using these gases, ¹²CH₃F, ¹³CH₃F, ¹²CD₃F and ¹³CD₃F, as FIR media about half of the frequency region from 8 cm^-1 to 73 cm^-1 can be covered with tunable intense pulsed radiation. We studied quantum effiencies and bandwidths of the tuning intervals for the different gases and also for different pump schemes.
