Transformation of Non-Diffracting Beams by a Telescope System
For non-diffracting beam generated by a axicon lens, its central spot diameter and non-diffracting distance are fixed. A new way to change the parameters of non-diffracting beam using a popular sphere lens telescope system is proposed based on the relationship of lens transform between non-diffracting beam and ring light source. The non-diffracing beam is firstly transformed to a ring light source by the first lens of telescope. And then the ring light source is transformed to a new non-diffracting beam with different parameters in terms of the second lens which has different focus. The new parameters are determined by the ratio of focus lengths of the two lenses.
