Abstract
As an extension of our previous study the area scintillation aspects of Bessel Gaussian and modified Bessel Gaussian beams of zeroth order are investigated The analysis is carried out on the basis of equal source sizes and equal source powers It is found that when compared on equal source size basis modified Bessel Gaussian beams always have less area scintillations than a Gaussian beam while Bessel Gaussian beams exhibit more area scintillations Comparison on equal source power basis however removes the advantage of modified Bessel Gaussian beams that is their area scintillations become nearly the same as those of the Gaussian beam On the other hand for the case of equal source powers Bessel Gaussian beams with larger width parameters continue to have higher area scintillations than the Gaussian beam We provide graphical illustrations for profiles of equal source size beams equal source power beams and the curves to aid the selection of equal source power beams
