摘要：
Beam-shaping optics are used in optical pick-up units to improve the optical power efficiency of the light path. In this paper a flexible method is presented to design beam-shaping optics with aspherical surfaces transforming the intensity profile of the light beam into any desired profile. The method is applied to a collimator lens that transforms a Gaussian beam profile to a flat top. (c) 2005 The Optical Society of Japan.
