Paper Abstract

The power in the bucket (PIB) and (beta) -parameter are chosen as criteria for characterizing the laser beam quality in the far field, the beam quality of annular lasers with or without phase distributions is studied in detail. It is shown that the better focusability is achieved at the real focal plane, and a suitable choice of negative phase distributions may improve the beam quality.
