Behaviour of pulsed vortex beam with high topological charge in ionized dielectrics

Khasanov O.K., Fedotova O.M., Smirnova T.V., Petukh Yu.N., Volyar A.V. and Sukhorukov A.P. 2008. Ukrainian Journal of Physical Optics 9: 10-21.

It has come to the attention of Editorial Board of Ukr.J.Phys.Opt. that this article should not have been submitted for publication owing to its substantial replication of an earlier paper (R.A. Vlasov, O.K. Khasanov and T.V. Smirnova 2005. Evolution of tubular singular pulsed beams upon ionization. Quantum Electronics 35: 947-952).

Consequently this paper has been retracted by the Editorial Board of Ukr.J.Phys.Opt.
