  • On the basis of analyzing far-field intensity distribution of pane-waves diffracted by a rectangular annular aperture, a detailed study of the beam quality has been made. Numerical calculation results have been illustrated. The results indicate that it is suitable to characterizing beam quality of this type of annular beams with power in bucket (PIB),β parameter and η parameter.On the other hand,the weakness of these methods has also pointed out.

Abstract: On the basis of analyzing far-field intensity distribution of pane-waves diffracted by a rectangular annular aperture, a detailed study of the beam quality has been made. Numerical calculation results have been illustrated. The results indicate that it is suitable to characterizing beam quality of this type of annular beams with power in bucket (PIB),β parameter and η parameter.On the other hand,the weakness of these methods has also pointed out.
