Paper Abstract

The focusing system is very important for laser processing, especially for laser micro-processing, whose characteristics influence directly the quality of laser processing. A new optical system from the potive axicon and spherical lens combination is proposed in this paper to generate the diffraction-free beam. Only one axicon is needed in this system to produce the variable diffraction-free beam spot of micro order by changing the ordinary cheap spherical lenses. If such an optical system is used as the focusing system for laser micro-processing, the sensitivity to the workpieces' position would be zero and the adaptability to the flatness of the workpieces' surface could be enhanced. Moreover, such a system could adapt well to the different processing criterion by changing the ordinary spherical lenses and would also have potential application in the measurement field.
