  1. We present a charge - transport model of the photorefractive effect with two deep traps ( two deep - trap model ) based on one deep - trap model and shallow - deep - trap model. we also found dark decay behaviors which accord with the two deep - trap model in the two - beam interference experiments. the fast decay - time constant of the space - charge field is obtained as 714s

    此外，在ce ： batio _ 3雙光束干涉光折變光柵的暗衰減實驗中，也觀察到了符合雙deep模型的衰減現象，得到光折變空間電場快衰減時間常數714s ，約12分鐘。
  2. Using the new excimer laser photorefractive keratectomy ( prk ), the molecular bond of the corneal stroma is broken to allow recofiguration of the cornealsurface. this photo - ablation effect can treat severe myopia, astigmatism, and a variety of corneal diseases using photo - therapeutic keratectomy ( ptk ). the safety, predictability, and long - term stability are well established in major western medical facilities

    準分子激光技術在國內、外安全使用十一年，並得到眾多醫學權威機構的認定，具有安全性及精確度高、可預測性強、長期穩定性好的特點，我院已為幾百名近視患者實施了這種手術， 90的患者術后視力達到1 . 0以上。
  3. Abstract : brief introduction to ( 2 ) cascading nonlinearities is presented. the enhancement mechanisms for optical kerr effect and the photorefractive effect as ( 2 ) cascading process are discussed. mutual inductance between quadric and cubic nonlinearities opens possibilities for engineering optical nonlinearities

    文摘:介紹了（ 2 ）串級非線性.討論了串級光克爾非線性和串級光折變非線性的增強機制，並指出二階和三階非線性的相互轉化，為光學非線性工程設計提供了可行性
  4. On the basis of these theories, detailed experiment investigations are carried out as follows : ( 1 ) the interference pattern of two - prism is adopted to illuminate linbo3 : fe crystals. then array of planar waveguides are fabricated in the crystals due to photorefractive effect

    在此基礎上，詳細地進行了以下幾個方面的實驗探討： （ 1 ）利用平行光通過雙棱鏡后所形成的干涉光場輻照linbo _ 3 ： fe晶體，在晶體中寫入陣列平面光波導。
  5. By examining the micro mechanism of photorefractive effect, we can find that an external dc electric - field can greatly alter ( improve or worsen ) the photorefractive properties of sbnrcr. so it is important to study electric - field effects in these materials. in this thesis, the characters of beam coupling and transmission in sbn : cr crystals under external dc electric - fields are investigated theoretically and experimentally

    本文依據光折變非線性光學的光波耦合理論和傳輸理論，對sbn cr晶體在外加直流電場作用下的光波耦合特性和傳輸特性進行了理論分析和實驗研究，主要內容包括： （ 1 ）從理論上分析了外加直流電場對光折變二波耦合增益的影響，給出了sbn 60晶體的強度增益系數隨外加電場變化的理論計算曲線。
  6. In photorefractive crystal light illumination changes the refractive index of the crystal due to linear electrooptical effect, which in turn changes the light distribution. as a result of the development of this process, a beam, called the phase conjugation wave, leaves the crystal back along the direction of the incident beam and is its phase conjugate replica

    光折變晶體在光輻照下，通過晶體中的線性電光效應而產生折射率隨光強的空間分佈而變化，即在晶體內建立起體相位柵。
