Paper Abstract

Polarization laser direct-writing system was designed and the recording and research using the azobenzence polymer film on the system was investigated. Only single laser beam was used, and move the laser focal spot on the sample film pointto- point. By composite control of the optical power density, polarization direction and exposure time of the inscribing laser, a special phase-delay distribution graph which have different etching depth in different point can be achieved. Diffractive devices, such as grating and zone plate, have been inscribed. The anisotropy and surface topography was measured by polarizing optical microscopy (POM) and profilometer. Some qualitative analysis was made. Using the red light which is insensitivity to the azo polymer film, the diffractive devices’ focal spots were collected by CCD. Compared with the holographic interference method, the method is more flexible, undemanding for the experimental environment and any two-dimension distribution graph can be written in theory. It may get extensive application.
