Study of evaluating nearfield beam quality of the high power laser beams

摘要

The nearfield beam quality of the high power laser system is of great importance in order to achieve a very good effect in the specific position. We review various aspects of evaluating this nearfield beam quality, present results obtained in a high power laser system, and discuss the valuable reference of beam quality improvement in the spatial shaping system for high power lasers.
