Regularization of complex beams

Abstract: The well known 2D complex-point-source beam presents undesired field characteristics. This paper proposes some combinations of simple complex beams which allow the construction of well behaved fields.

“…From the physical point of view, the complex displacement of the source location, ib, has important interpretations which require the study of the delta function of complex argument, [8,14], but this fact is out of the purposes of this paper. From the mathematical point of view, a displacement ib of the source is equivalent to a displacement −ib of the observation points as it was established in Section 2.…”

“…This solution has been proposed in order to extend the validity of the GB beyond the paraxial zone and exhibits the required cylindrical symmetry. Using the Green's function of the inhomogeneous Helmholtz equation for a point source located in complex space at coordinates x = ix R and y = 0, one obtains the CSB solution [68] ϕ i (r) = H…”

“…The waist plane is thus located in the branch cut. It should be noted that to obtain a regular solution in that plane, one can combine linearly independent CSB solutions as described in [68]. The CSB solution reduces, up to a multiplicative constant, to a canonical Gaussian beam in the paraxial zone x y.…”

“…The CSB is continuous everywhere in the real plane except across the branch cut connecting the two singularities at (x, y) = (0, x R ) and (x, y) = (0, −x R ). For the purposes of this paper, we shall restrict our attention to scatterers located in the positive x plane, referring the reader to [26] for regularization strategies in the waist plane. Since the H (1) 0 function converges rapidly to a complex exponential, one can readily show that, for x > 0,…”
