Abstract
The testing results of a homodyne 0.195-mm laser interferometer-polari meter based on quasioptical components are presented. The int interfer ometer-polarimeter matched to the multichannel interferometer of a Tok amak-15 machine admits of simultaneous measurements of the plasma elec tron density and poloidal magnetic field in one of the seven vertical- probing channels without any disturbance in the others. The achieved r esponce threshold of the electron density is 3.4.10(11) cm(-3), the po larization resolution and the phase difference measurement error are n o worse than 0,1(0) and +/-4(0), respectively.
