摘　　要：ＬＡＰ是一种新型的有机非线性光学晶体，由于其优异的性能，成为很有希望取代ＫＤＰ晶体，应用于激光核聚变反应的晶体。本文探讨了ＬＡＰ晶体溶液降温法生长过程中易出现的母液变色和细菌污染问题，找到了一种效果更为理想的防菌剂－液体石蜡。通过来取低温生长和防菌措施，解决了上述问题，长出了光学质量好的ＬＡＰ单晶。LAP is a new nonlinear optical organic crystal, for higher damage threshold and harmonic generation in place of the conventional KDP in the laser fusion programme. In this paper,the discolouration and microbes pollution of LAP solution by slow-cooling were indevestigated. A new inhibitor-liquid paraffin with better effect was found. By keeping the growth temperature low and preventing it from microbes, we obtained high-quality single crystals of LAP.
