Abstract

Abstract

The influencing factors of beam quality βfactor of high-energy laser system is analyzed based on two-dimension chirp ztransformation. The effects of the sampling number within the diffraction limit and the beam spot’s energy loss on the beam quality βfactor are analyzed. The simulation results based on different sampling numbers indicate that a larger sampling number induces higher beam spot diffraction image resolution which is beneficial for more accurate calculation of a beam quality βfactor. When the sampling number of the diffraction limit angle is no less than ten, the measurement error can be limited within 3%. Meanwhile, different wavefront aberrations have different sensitivities against beam spot energy loss. The beam quality βfactor of high order wavefront aberration is larger than that of low order aberration with equal energy loss. Especially, the spherical aberration is most sensitive to energy loss, and about 5% energy loss can induce 15% to 30% calculation error of the βfactor.
