摘要：

A novel method for forming pure helical laser beams of pre-determined helicity is presented. It is mainly based on replacing one of the laser mirrors with a spiral phase element. The basic principles along with experimental results using a CO2 laser are described. (C) 2000 Elsevier Science B.V. All rights reserved.
