Transformation properties of laser beams passing through axicon system and their applications

In this paper,the transformation properties of the He-Ne and CO2 laser beams passing through a axicon system has been experimentally investigated in detail. Based on the geometrical optics,the optieal transformation properties of the axicon system are also analysed. For some practieal applications,the schemes of the uniform line focucing and the annular beam are prope and have high transformation efficiency. The speem can be widely used in laser processing,beam alignment and focucing.
