Abstract
Two-wave lasing in the far IR range has been used in an interferometer , whose advantages are improved stability under adjustment errors, imp roved informativeness, and reduced costs by comparison with the use of two or more lasers. Two promising line pairs have been examined: 118. 8/170.6 mum and 184.8/298.7 mum on pumping correspondingly the vapors of CH3OH and CD3OD. A two-wavelength laser interferometer has been tes ted in which the two interference patterns are recorded simultaneously .
