摘要：

Super-Gaussian-Bessel (SGB) beams that have the form A exp[-(r/w)(n)]J(0)(alpha r) are introduced. The numeric calculations show that there exists an optimal n that is dependent on w alpha only. The SGB beam with optimal order n is the best ''non-diffracting'' beam, its transversal intensity distribution is practically unchanged within some propagation distance. The relation of optimal n versus w alpha is obtained through numeric calculations.
