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:用離子交換法制作的電光波導,其離子交換濃度、折射率變化符合余弦誤差函數(shù),光學均勻性以及器件的溫度穩(wěn)定性較好;制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 ;制作的電光調制器用于激光脈沖整形試驗,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(xiàn)晶體變黑現(xiàn)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。
