    • Abstract
  • In order to collimate and shape the LD beam with astigmatism, the mathematic condition for LD beam shaping with a cylindrical gradient-index lens was introduced applying ABCD law. Based on this, a system with good effect was got through software simulation. After collimation and beam shaping, the beam in fast and slow axis has the same divergence angle which is less than 0.7mrad and the beam waist difference in z axis is less than 2.8mm. The result shows a good effect was obtained with a cylindrical gradient-index lens in this system. Under the condition of beam shaping and collimation, the LD beam has the characteristics of small divergence angle and rotationally symmetry.
