Abstract

The depolarization of a linearly polarized laser beam was investigated primarily with an optical path of 4.5 km. A He–Ne gas laser at 6328 Å was used with an additional polarizer at the output and with a rotating polarization filter assembly in front of the receiver. Values of depolarization found ranged between 10−7 rad and about 5 × 10−5 rad. The lower limit was determined by the quality of the polarizer-analyzer combination used. These experimental values of depolarization are very much higher than that predicted by theories regarding turbulence-induced depolarization.
