The first far-infrared laser scattering measurements from a tokamak plasma are reported. Spatially and temporally resolved power spectra of density fluctuations in the Microtor plasma have been studied with an absolutely calibrated far-infrared scattering system which allowed measurement of the wide range of wave numbers from k=3 to 50 cm/sup -1/. The wave-number dependence of the scattered power of 0.6< or approx. =k/sub perpendicular/rho/sub i/< or approx. =2 was found to satisfy a k/sup -3.5/ form.
