Abstract
We design a free-form lens, which can reshape a Gaussian green laser beam into a top-hat irradiance distribution over the target plane. We measure the laser beam profile of every part of this green laser beam shaping module. The divergence angle of the green laser module is not wide enough for laser level system. We can get a wider divergence angle of the green laser beam system when adding the beam shaper and the cylindrical lens. The divergence angle of the green laser level system is about 120° and the uniformity of the green laser level system is about 91.08%.
