Abstract

The laser beam space uncertainty σ was measured during ray propagation in atmospheric air (a) and in atmospheric air inside the tube (t) with both ends closed by optically transparent windows. For the studied case of the 70 m passed distance, the sigma values were discovered to differ greatly: σ a t ≈ 100 x . The observed effect may represent a physical basis for the creation of an extended laser ray to be used as a coordinate axis in the high-precision metrology when assembling a big-length research equipment (accelerators, detectors, etc.) or in civil engineering tasks.
