Abstract

Measuring far-field laser beam profile is an effective way to study the atmospheric transmission effects of high power laser in a long distance and evaluate the technical performance of high power laser system. Diagnostic technologies for measuring the far-field high power laser beam profile are summarized and their applicable scopes are described. The measuring method based on spatial sampling discrete detector arrays is mainly introduced. Finally, two types of laser beam profilers based on detector array are presented, which are developed by our group recently, and they are respectively suitable for measuring far-field continuous wave high energy laser and high repetition rate pulsed laser.
