Abstract

The diffraction-limited multiplier factor β is one of the important indicators for evaluating the energy transfer performance of an optical system. It can reasonably evaluate the beam quality and reflect the actual laser beam energy transfer efficiency and focusability. Starting from the basic concept of β factor, this paper discusses the calculation method of β factor, analyzes the characteristics of β factor, and discusses the engineering application method of β factor based on actual engineering experience, which provides a reference for high-energy laser β factor engineering testing.
