生长了优质的ＫＮｂＯ＿３：Ｒｂ晶体，研究了光折变时间响应特性。发现该晶体的光折变响应时间可分为快慢两个成分，快成分占７０％。在总写入光强为１Ｗ／ｃｍ￣２时，快成分可达２ｍｓ。该晶体不需进行还原处理，光学均匀性不会因此而遭到破坏。
Growth of high-quality KNbO_3: Rb crystals was studied photorefractive time response characteristics. Found that the photorefractive crystal response time can be divided into two components fast, 70% of fast components. In the total write intensity of 1W / cm ~ 2, fast components up to 2ms. The crystal does not need to be subjected to the reduction treatment, and the optical uniformity is not damaged.
