磷酸二氢铵（ADP）是KDP型晶体家族中的一员，作为大尺寸晶体应用于人们的生产实践中由来已久。由 于其具有激光倍频效应、电光效应、压电效应等多种特殊功能，所以关于ADP晶体的研究应用一直为人们所关注。
Ammonium dihydrogen phosphate is a member of the KDP family and has been widely used as a large-sized crystal in people's production practice for a long time.Because of its many special functions such as laser frequency doubling effect, electro-optic effect, piezoelectric effect,etc.,the application of glasses forADP crystals has been concerned.
