It is well known that β-BBO is a new type nonlinear optical crystal discovered in our institute and now β-BBO is widely used in the fields of laser and nonlinear optics. However, there are still some inclusions in β-BBO crystal grown by flux method. Using AEM technique, we have studied the shape, composition and structure of inclusions which is very helpful to the explanation of
