摘要：

This work presents an effectively implemented calibrated polarization-independent Fresnel attenuator of laser radiation power built on the basis of two Dove prisms. A method of the attenuator's alignment with a laser beam axis as well as of determining the main axes of laser radiation polarization is herein demonstrated. It is shown and experimentally proved that using model calculations the prisms' manufacturing and assembly imperfections can be compensated by the attenuator's rotation by certain angles and a corresponding change of the system's total reflection coefficient.
