The results of theoretical and experimental investigations of two crystal travelling-wave optical parametric generator (TOPG) are presented. It is shown that the efficiency and angular structure of TOPG output depends on the distance between crystals. The experimentally observed efficiency modulation is attributed to air dispersion and this is confirmed by theoretical calculations.
