Quality control of quarter-wave plates
Coordinate dependences of the phase difference and the orientation of the optical indicatrix along the diameter of the quarter-wave plates of different quality.

Control of the quality of installation of the active element of a solid-state laser
When mounting an active element in a quantum node, mechanical stresses may occur, which will lead to changes in the optical characteristics of the active element and the deterioration of laser generation.
