Paper Abstract

The results of research work on laser modes influence on contrast ratio and on microgeometry of marks created on the finished surface of beryllium gyro details are described. Within the research the possibility of getting the required contrast ratio 0,7±0,1 on the wave length 860 nm due to laser marking usage is presented.
