The divergence of laser beams is usually decreased by beam shaping Galilean telescope optics, Keplerian telescope optics are not suitable for this purpose because of resulting excessively high energy concentrations. The use of a Galilean system alone requires an appreciable enlargement of the objective diameter. This enlargement can be reduced by a modification by insertion of a converging lens with a focal length of f (sub l) d (sub l) l (sub gamma l) between the laser exit window and the ocular. The exact location of this lens is determined by the system geometry and dimensions and the maximum allowable energy concentration at optical surfaces, considering that the ocular diameter should be the smallest possible. The proposed method allows much design flexibility.
