This paper is a review on the generation of far-infrared (FIR) radiation via stimulated Raman scattering in methylhalides by the use of a frequency tunable 20 atm CO2 laser as pump source. A survey on the properties of the methylhatide molecules was achieved by studying the seven gases (CH3F)-C-12, (CH3F)-C-13, (CD3F)-C-13, (CD3F)-C-13, CH3Cl, CH3Br and CH3I. All these gases turned Out to be well suitable media for generation of tunable FIR radiation with the lightest of them having the most favourable emission characteristics. With the pump laser applied, frequency tunable FIR radiation was obtained from the seven gases for more than 600 Raman tuning ranges covering almost the complete frequency range from 8 to 72 cm-1. It is also demonstrated that the broad tuning ranges and the high maximum quantum efficiencies up to 0.1 can be used for generation of intense FIR pulses with subnanosecond duration.
