Abstract
Phase aberrations are ubiquitous in optical systems and can lead to the degradation of laser beam quality. The laser beam quality factor is an important parameter that can be used to determine the quality of a laser beam. In this work, we derive analytical expressions for the beam quality factor of Laguerre-Gaussian beams due to different types of astigmatism: 0° astigmatism, 45° astigmatism, x-triangular astigmatism, and y-triangular astigmatism. The results show that the beam waist radius is an important parameter in determining the effect of astigmatism on the beam quality factor of LG optical beams.
