The Reason of Causing of Light Scatter in Pyrophosphate Doped KDP Crystal and its Elimination

Pyrophosphate doped KDP crystal was grown from aqueous solution by the temperature lowering method. Light scatter in KDP crystal was detected with an ultramicroscopic method. It has been proved that light scatter in KDP crystal aggravated when pyrophosphate was doped into the growth solution, which distributed non-uniformly in prism and pyramidal sectors of the KDP crystal. The different effects of pyrophosphate on prism and pyramidal sector of KDP crystals can explain this case. The method of eliminating light scatter in pyrophosphate doped KDP crystal is discussed.
