Application of the manipulated vectorial laser field in surface treatment

In order to study application of the manipulated vector laser field in surface processing, based on Nd:YAG pulse Q-switched laser, vector control module was built. Laser ablation drilling experiments on titanium alloy and silicon was used to study effect of pulse number of cylindrical symmetric vector laser, the polarization of beam and the topological charge on laser surface treatment. The results show that the influence of laser pulse number on hole is mainly concentrated on hole depth and aperture. The polarization of beam mainly affects the roundness and smoothness of the hole. Topological loads affect the smoothness of the bottom and periphery of the hole. As a special kind of laser, the manipulated vector laser is expected to be widely used in the field of fine material processing.
