  7. The tests of e - o applications by our flux ktp has been realized, the results showed : optical waveguides fabricated by using an ion - exchange process, which have an exchange - ion concentration depth profile and refractive - index profile, is close to a complementary error - function distribution, optical homogeneity and device thermal stability is much better. amplitude modulation switch formed by our flux ktp has the contrast ratio of 150 : 1 and insert loss is 2. 5 % at 1064 nm. high quality optical pulse with 1 ns width was cut successfully by using an e - o modulator from a laser pulse with 50 ns width, this modulator had run for three years, and the crystal did n ' t blackened, it showed our low conductivity flux ktp can endure high modulation voltage for a very long time

    Ktp晶體的電光應用試驗表明：用離子交換法製作的電光波導，其離子交換濃度、折射率變化符合餘弦誤差函數，光學均勻性以及器件的溫度穩定性較好；製作的強度調制電光開關，消光比為150 ： 1 ，對1064nm激光的插入損耗為2 . 5 ；製作的電光調制器用於激光脈沖整形試驗，從脈沖寬度50ns的激光脈沖削出脈寬1ns的高質量光脈沖，該電光開關經過長達三年多的使用，沒有出現晶體變黑現象，說明本實驗的低電導率ktp晶體能夠耐受長時間的調制電壓。
