%X When a single spherical mirror is used to compress laser beams, there usually is a problem that the poor divergence can be resulted in or too many spherical lenses have to be used. By using a ABCD matrix method to analyze the Gauss beam passing through a single lens in theory, a conclusion that the beam from a semiconductor laser can not be collimated ideally with a single lens is drew. A design scheme based on ZEMAX is proposed for the collimation of a semiconductor laser source. The design and optimization method is given. For a 808 nm semiconductor laser commonly used in engineering, a collimator with two lenses is designed and its aberration is corrected by using the proper optimization function and weight in ZEMAX. By using a non-spherical surface, fine collimation is implemented at a divergence angle of 0.032 mrad. This design has the features of less lenses and simple structure.
