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...
This force causes the flat disk to be flexed into a substantially spherical, nearly parabolic shape. The magnitude of the force applied controls the degree of flexure and hence the focal length of the spherical mirror. For laser beam focusing the materials are selected to be able to withstand ...
