Abstract
The hollow beam has a variety of special physical properties and can be applied to the optical catheter, optical trap, generation of the light trap and many other important fields. In this paper the light-field conversion of the Gaussian beam passing through double axicons and generating the hollow beam is theoretical derived and simulated using the light-field propagation method. The influence of several parameters on the near and far field intensity distribution of the hollow beam is discussed. We find that the hollow beam with different light-field can be generated by controlling these parameters and this has a great potential in terms of micro manipulation, optical trap and other fields.
