  1. It is well known that nonlinear self - focusing effect is one of the important factors to limit icf laser energy and worsen beam quality

    實踐表明,非線性效應是限制icf驅動輸出能量及破壞束質量的主要因素之一。
  2. According to the guidline, two nd : yag lasers have been designed and set up, one is end - pumped by lower output power ld using a selfoc micro lens, and the other is end - pumped by high output power ld using a pair of lenses are designed, and the characteristics such as output power and power stabilization of both solid - state lasers are investigated. thirdly, when an empty liquid crystal cell is inserted in the cavity of the nd : yag laser pumped by high power ld, the laser can operates in single axial mode. finally, according to the relationship between the laser output power and the longnitudinal a ld - end - pumped nd : yag laser sensor for displacement measurement has been investigated theoretically and demonstrated experimently, the results indicate that when the mean radius of pumping inside the laser cavity is far less than that of the oscilating laser mode, the exponential of the output power is a gauss function of the longitudinal positon of focused spot of ld pumping beam, both the measurement range and the sensitivity are dependent on the incident pumping power, as the incident pumping power is increased, the measurement range is enlarged and the sensitivity is improve d

    本文首先介紹了ld泵浦nd : yag的發展狀況、主要特性及其應用,從四能級速率方程出發,推導了ld泵浦nd : yag的閾值、輸出功率和斜效率的表達式,並簡述了的工作原理、結構型式和倍頻方法;其次,以空間相關的速率方程為基礎,提出了ld端面泵浦nd : yag的設計方法,給出了一定泵浦耦合方式下,振蕩模尺寸、最佳輸出耦合率、泵浦模尺寸、泵浦斑位置等參數的選取依據,以此為依據,設計了透鏡耦合小功率ld泵浦nd : yag和透鏡組耦合高功率ld泵浦nd : yag,對的輸出功率和功率穩定性等特性進行了實驗研究;再次,在帶尾纖輸出的高功率ld泵浦nd : yag腔內插入一隻空液晶盒,觀察到了以單縱模運轉;最後,根據泵浦斑端面位置對輸出功率的影響規律,提出了ld端面泵浦nd : yag位移傳感新方法,並進行了理論和實驗研究,研究結果表明:當晶體內泵浦平均斑半徑遠小於振西安理工大學碩士學位論文蕩束腰半徑時,輸出功率的然指數與泵浦斑的縱向位置成高斯變化規律,測量范圍和靈敏度依賴于泵浦功率,隨著泵浦功率的增加,測量范圍擴大,靈敏度提高,當端面泵浦功率為7 . 24w (最大輸出功率為1 . 926w )時,位移傳感的測量范圍和靈敏度分別是13 . 045mm和0 . 148mw / pm 。
  3. In high - power solid - state lasers, self - focusing is the major factor for degradation of laser beam and limits the maximum laser power available. as stated in lowrence livermore national laboratory ( llnl ) reports, self - focusing, especially small - scale self - focusing, has always been a significant problem in the total design, engineering development, and safe operation of fusion lasers

    在用於慣性約束核變( icf )的高功率固體驅動中,是使束質量變壞和限制輸出功率的主要因素,正如美國勞侖斯?利弗莫爾國家實驗室( llnl )的報告所述,,特別是小尺度,是總體設計、工程研製和安全運行的重要問題。
