| Abstract: | The propagation of astigmatic beams in free space is studied in detail by using complex wavefront matrices Q-1,Q, the concept of complex ray vector and the generalized ABCD law. The characteristics of astigmatic Laser beams propagating in homogeneous free space are discussed, and numerical calculations are performed to illustrate the results. |
| Keywords: | astigmatic beam complex wavefront matrix complex ray vector generalized ABCD law. |
