Design of the Laser Beam Renovating System Outside Laser Cavity

In the light of the principle of wave optics and the theory of optical wave front transformation and modulation from transmission diffraction bodies a combinatotial laser beam renovating system outside laser cavity is designed. The system is composed of transmisson elements, each one is designed according to the distribution of transmisson rate function. After the laser beam from the laser goes through the system, the optical wave front is modulated and renovated.
