Abstract:
The positions of the planes with different states of the structure of the radiation in the far-field zone of focusing optical systems were determined theoretically and experimentally for multichannel lasers as a function of the focal lengths of the focusing systems and of the distance from the exit window of a laser resonator due to the focusing system. An analysis was made of the influence of the radiation structure on the formation of the zones of the laser interaction with steel under different laser processing conditions.
