Abstract
A number of investigations have been performed at XEOS for the purposes of: (1) characterizing the time-dependent polarization states of the 632.8 nm output beam of internal mirror He-Ne lasers, and (2) evaluating the effect of beam polarization on the Bragg diffraction efficiency of an AO modulator. The results of these two lines of investigation have suggested that, under certain circumstances, extraneous fluctuations or noise can be induced in the diffracted beam by polarization fluctuations of the laser beam. It is the purpose of this report to define the conditions under which polarization induced noise is produced, to evaluate the magnitudes of these effects, and to suggest practical methods by which polarization noise can be eliminated.
