The Review of the Study on the Growth Mechanism of KDP Crystal
KDP crystal is a typical artificial crystal and be grown in an aqueous solution.It has excellent nonlinear optical properties and can be easily grown into large-size single crystal.The frequency-doubling devices in the project of inertial confinement nuclear fusion(ICF)were made from it.However,cracks and inclusions are easy to occur during the growth process of large crystals,which can affect the physical properties of crystals.The exploration of the growth mechanism and the improvement of growth technology of this kind of crystal have been carried out.In this context,this paper summarizes the main research methods on the growth mechanism of KDP crystal in the past half century and compares their advantages and disadvantages.Besides,the related research results are introduced.This paper can provide a reference for other studies on the growth mechanism of aqueous solution crystals.
