Abstract

According to the mode and focus characteristic of the laser beam, a laser focus mirror is developed based on the designing principle and method of analytical function non-spherical focus mirror(ANSFM), its designing and focus characteristic is analyzed systematically. The result indicated: With this design technique, numerous iterations and experienced parameters are not needed, comparing with the designing of high order multinomial non-spherical focus mirrors(HONSFM). Once the focal length f ,diameter D and refraction index n of mirror material are known, the analytical non-spherical focus mirror can be obtained accurately and fast. The designed mirror has flat surface and large machine tolerance, which makes it easy to be manufactured and tested. The focusing spot diameter(FSD) of the designed mirror is φ11.4μm for a parallel beam. The experimental results show that FSD_ANSFMHONSFM
