Abstract
It is hard to design for beam expander with high-power and wide-aperture required, because it is shorten length, larger aperture, as well as on-axis and off-axis aberration must be corrected properly. A design method for high-power and wide-aperture beam expander is talked about. One beam expander is given with clear aperture of 200 mm, focal length of 400 mm and field of view of 2 mrad. Image evaluation and system parameter are shown at same time.
