Abstract
Properties and practical applications of the light beams with helical dislocations (HD) of wavefront in metrological systems are considered on the basis of experiments with gas lasers and numerical ones. It is shown, that the super stable lasers-heterodynes with high quality of out coming radiation can be created using lasers with inner-resonator helical fields. Conditions of HD appearance in laser beams propagating through the turbulent atmosphere are determined. A method of definition of atmospheric turbulence degree based on HD number counting is suggested. The possibility of such beams application in metrological optical systems having super Raleigh spatial resolution is considered as a promising direction of their usage.
