  1. 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

    在用於慣性約束核聚變（ icf ）的高功率固體激光驅動器中，自聚焦是使光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，自聚焦，特別是小尺度自聚焦，是聚變激光器總體設計、工程研製和安全運行的重要問題。
  2. In a laser - powered plasma accelerator, an ultrashort laser pulse is focused into a helium jet that is a couple of millimeters long

    在雷射電漿加速器里，一個超短的雷射脈沖聚焦到一束大約兩、三公?長的氦噴射氣流中。
  3. Common focus point gather migration velocity modeling based on constraint parameter inversion

    基於約束參數反演的共聚焦點道集偏移速度建模方法
  4. We discuss the effect on the focusing of the probe beams for the five initial parameters : the amplitude of the pump beam, the separation between the pump and the probe beam centers, the wavelength ratio of the pump and the probe beams and the ratio of the initial beam widths at the directions of x and y. our numerical results show that, more the amplitude of the pump beam, the wavelength ratio of the pump and the probe beams and the ratio of the initial beam widths at the direction of y, more the probe focus ; the separation between the pump and the probe beam centers and the ratio of the initial beam widths at the direction of x have optimum values, respectively

    研究了泵浦光束輸入振幅、泵浦光束-信號光束初始偏移、泵浦光束-信號光束波長比和泵浦光束-信號光束x 、 y方向的初始束寬比五個參量對信號光束聚焦程度的影響。數值模擬結果表明，泵浦光束輸入振幅越大、泵浦光束-信號光束波長比越大、 y方向束寬比越大，信號光束聚焦程度越大；泵浦光束-信號光束初始偏移和x方向初始束寬比都存在一個最佳值，使得光束聚焦達到最佳效果，有趣的是這兩個最佳值的比值基本保持不變約為0 . 4 0 . 6 。
