Abstract
This work examines an attenuator of laser radiation based on four Dove prisms, which is much more efficient in comparison with two cascades of a di-prismatic attenuator. In this case, not only is its alignment and assembly significantly simplified, but also the consistency of the construction becomes evident. It turns out that the most optimal configuration of a four-prismatic attenuator is a pair-parallel one. This configuration, compared with a pair-perpendicular one, provides exchangeability of the di- and the four-prismatic model of the attenuator, maintains the direction of propagation of the radiation, and has a reference beam to control an attenuation coefficient in the operation process of the attenuator.
