  1. 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。
  2. In order to reduce the influence of the laser diode ’ s heat effect, a thermal control device is designed to make laser diode work under a stable temperature. the principle and application of ic - wkn is researched adequately. a signal modulation circuit including d / a converter and chip computer is designed

    由於溫度變化也會影響到半導體激光器的正常工作,為了減小環境溫度變化和激光器的熱效應對激光器本身及其輸出造成的影響,本文將半導體激光器和溫度控制裝置設計在一起,使激光器能夠在恆溫下工作。
